Ruger Mark III 2245 Magazine Tuning Tips and Tricks | TANDEMKROSS

[@danulman8837]

This may be eight years old but I have never come across an online “how to fix it” video that had a greater impact on turning a brand new firearm from a total jamomatic to 100% reliable. 👍

[@ronneaves550]

I’ve got on that has never worked right. This is my answer.

[@aaronstallings4852]

Since (apparently) KZbin commenters appear to have achieved an average age of thirteen, (which makes the presence of such spiteful people on a gun video dubious...) let me point out that nobody here claimed to have invented this process. This video is just Tandemkross showing people how to do it. That's it. Just a tutorial. Can we all just go back to enjoying the free exchange of ideas now? LOL Keep up the good work, TK! Never given me reason to so much as consider sending anything back.

[@perrysimons9379]

I was having about a 20% FTF or stove-pipe failures on my Mark IV Hunter. I had tried all types of ammunition with no improvements. Then I came across this video. I "tuned" two of my magazines and after running about 300 rounds through . . .NO FTF or stove-pipes. Great tip and easy to follow instructions. Now onto my other mags.

[@TANDEMKROSS]

So glad to hear that, Perry! Thanks so much for the feedback

[@fredmeebley]

On the subject of trying different types of ammo, CCI minimag and Blazer seem to work best for me.

[@Sparky_GT]

Thanks Perry and Tandemkross for the info on the MKIV, im going to give it a shot as well.

[@livelifetogivelife9462]

Thank you! For YEARS my son has wanted an old Ruger Mark 22. I always attempted to redirect him. Well 2023 Christmas was special and I knew what he wanted :) With your help his new toy will be VERY enjoyed. It’s also another good friendship builder for us. 👍🏼

[@defcon1526]

How has his ruger been? Whitch one did you get him? Mk-1,2,3, or 4?

[@unclefuzzy9802]

I recently bought a Mark IV Target and was having frequent problems with stovepipes and jams with ammo from three different manufacturers. I finally tried some CCI Mini Mag and that helped with only 2 stovepipes in 8 mags, a significant improvement. However, I wasn't satisfied and decided to tune my 4 magazines with a couple omissions. I ground the sharp points as instructed by Bryan, deburred the edges on the top as well as the button track and sanded the edges of the follower. I decided NOT to polish everything because I'm lazy and my magazines are already smooth plated nickel and not blued. I ignored the plunger and replaced the follower buttons with new TK buttons. THE RESULTS WERE AMAZING!!! On a test run, I shot 80 rounds of Federal Champion that had been a problem before and another 40 CCI Mini Mag with no troubles at all. A week later (and without cleaning), the wife and I shot 240 rounds of CCI Mini Mag with zero problems. The wife even noticed how much smoother the magazines were when reloading. In order to test how low we can go with this magazine tuning, I'll have to try some of the crappiest ammo I can find and see what happens. THANK YOU TANDEMKROSS!!!

I just discovered your video after analyzing a SR 22 mags that are rounded and MK II which are sharp and proceeded to do what you just showed , Super informative. Works great.

[@jeffwest5308]

I am a buyer of TandemKross products and will continue to be in the future. I find their products are quality made and reasonably priced. As a competitive shooter I have been tuning magazines of various types since 1990. This video on tuning Ruger mags is very well done and incorporates a couple things I had not thought of in the process. Good job Brian, keep up the good work. As for this Wood guy, nothing in Brian's video is really new, he didn't claim to have "invented" the process and whatever issue you have with him and the company seems to stem from your attitude alone. I would hate to live my life with your attitude.

[@tmadger3905]

Instead of using gun oil, I used Dupont Non-Stick Teflon Dry-Film Lubricant. I got the spray can. I used it on the spring, follower, and button. It's dry, doesn't attract grit, reduces friction, and bonds to the surface.

[@johntouse4611]

Your comments about removing burrs n polishing apply to MarkIIII mags just as well. 👍👍

[@Ryan-dk4gu]

This made a huge difference for me. I also lightly sanded the spring with 1k grit and deburred the end of the spring that travels. All my magazines function smoothly now, 250 rounds tested with no failure to feed issues. Thanks for posting this video.

[@TANDEMKROSS]

Glad it helped!

[@saskikojiro3214]

Man, this video saved me so much trouble. I was almost ready to give up, ran into this video followed it and now I'm having no problems. Thanks Tandemkross!!!

[@TANDEMKROSS]

Glad to hear it helped!

[@Three_Eyed_Willy]

I find it rather amusing that anyone living would claim to have "invented" or "originated" the principles of polishing and deburring magazines. This is information that has been used by people who wanted to smooth out all the parts of their semiautomatic pistols, since the advent of the P-01. It's basically the same principles that were used by people who did action jobs on their revolvers before CNC machined parts were available. I learned some of this from Joe Bowman in the 1990's. I'm glad to see this is up here and available. There is no earthly reason for anyone to tolerate badly tuned magazines. Thank you, Brian, and all the other folks at Tamdemkross!

[@statikhouse_kikz606authent5]

Can u do this on all metal magazines and it will increase performance such as a 1911 mag?

[@tmadger3905]

The space where you grind the two corners is very tight. There is a perfect Dremel item for that, #453. It is a 5/32" diameter by 3/4" long stone used for sharpening chain saws. Both Home Depot and Lowes have it in stock. There is a picture of it on both of their websites.

Well , I got to say the magazine tune up worked perfectly, my 24 year old Mark II ran great , this is a easy trick to complete, I also replaced 11 of the magazine springs and did a complete tear down and clean after the grinding and polishing . For my third steel match I was 13 out of 46 . Great video and thanks again .

Awesome! That's great to hear! Thanks so much for watching the video and for the feedback.

Great video, finished off my tune up on 11 markII mags and 13 markIII mags , about 5 hours in garage bench , these are 24 years old markII mags , so are the pistols . The markIII is five years old never a stovepipe or FTE or FTF . Had a double feed Saturday at a steel plate match . I'm looking to improve my time with the pistols I have , 24 years prices have went up along with ammo , Rimfire . Thanks

My Ruger Mk IV Lite has been a literal flawless machine for over 2K+ rounds, then suddenly started acting up. Naturally I suspect the mags. I'm starting with a takedown / clean, and we'll see where that leads - thanks for the vid!

[@proudcanadian9816]

Hi Brian, thanks BIG TIME for posting this mag tune how-to. In the past 6 months I purchased 3 22cal pistols; - 1988 unfired Smith & Wesson model 41 - A used but great condition Browning Buckmark URX 5 1/2" - A brand new Ruger Mark IV. Since 2 of these guns are unfired, and 1 is hardly used, (plus I bought 4 mextra mags for each gun to total 6), the mags are in need of your tuning attention. You know, the plastic followers have sharp edges from the cast molds, the mag frames are sharp from forming and cutting to shape, the top of the mag lip that holds the first round when you insert the mag is sharp...etc etc just like you described in your video..... Now I have 18 mags to tune up..... 🙄😔 thanks to you and your video... 😜 Seriously though, thanks for the great detailed instructions, perfect lighting, and focused video images to compliment the task

[@TANDEMKROSS]

So glad you found it helpful! Thanks for watching, Mike.

[@rogerscott9332]

Nice. I just ran the follower up and down a couple times and you can feel the resistance. Will definitely be doing this mod.

[@aaronotto7010]

Thank you for putting this out there. First 5 rounds of every mag are hosed. 3 different types of ammo. The last 5 seem to run great. Gun is brand new with one of your triggers in it. Will do this work in the next couple days and bring the gun back out to the range. Fingers crossed!

[@bobb9372]

Thanks for info. My mags feel gritty and sometime the follower gets stuck and causes a failure to feed. I feel confident that this is going to help a lot.

[@Istaphobos]

part of this reason is that the spring is on the side of the magazine, rather than the center, delivering oblique force, as compared to a Beretta Unos or SW mag. It those cases the force on the follower is centered as the spring itself is so placed, provided for a much smoother mechanism that the Ruger mags can never achiever, regardless of how much smoothing, polishing, and lubrication you apply. This doe not affect performance, but those pother butter smooth mags are much more pleasant to load.

[@bowl1820]

Thanks for this info! It Fixed a new mag not inserting issue I had. I got a Mark IV 22/45 lite about a month ago, I Just got a new magazine from TK and it wouldn't insert. I found one edge of the magazine was catching on the magazine latch and I had to press the mag. release to let it fully inset. I contacted Ruger and they exchanged the Mag. and sent me two new mags. which did the exact same thing! Comparing the new mags, to the ones I already had that worked. I saw the edges of the new mags were kind of sharp not as rounded as the old mags. So I followed this guide and did a little extra smoothing and polishing in the trouble area of the mag. They slide in like BUTTER now!

[@TANDEMKROSS]

That's so great to hear! Glad you found this helpful. Thanks for watching :)

[@qquuaadd1]

Finally got around to doing all this after my mkii wouldn't even chamber the first round anymore at all. To be honest I've never cleaned inside the magazines either... between doing what's on the vid and cleaning the two guns magazines I have they're all cycling like Champs now!! Mkii Mkiii

[@TANDEMKROSS]

Glad to hear it worked for you! If you're having issues with your firearm, cleaning it and your mags is usually a good (and free, more or less) place to start trying to solve the problem.

[@TheGoatMumbler]

This looks like a winter project in the man cave if you have more than a couple mags. Thanks for making my list longer. :)

[@wherearetgepoank1117]

I realize I’m commenting on a four year old video but I’m just curious what the bluing is for. I was under the impression that cold bluing really doesn’t convey the benefits that the actual factory process does ( hot bluing) so I was wondering how it affects the magazines.

[@jasoncapella]

Helps prevent rust and give a uniform look.

[@scottouellette8458]

Well thanks, now I have 7 mags to tune up there goes a half a day just kidding thanks for the tips. I use my mark 3 and my 22/45 for bowling pin and steel plate races any tips to help win are welcome.

[@kodiakfamily8032]

This was fantastic!!!!! Thank you!!!! I bought the Mark IV 22/45. When I shot it, horrible - 2-3 rounds per magazine didn't load and most got bent. So, I did this, all but bluing - I didn't have it. It's a totally different gun. Zero malfunctions today. Shot 120 rounds. Smooth! I love this gun! I was going to take it back, but no way now. Thank you for doing this!!! Though I think it's a shame that Ruger can't correct this in the factory

[@89Buffalo]

I have SPs when my Mark III is dirty (approx 75 - 100 rounds) so I tried this tune-up. Great presentation and easy to follow, but following the completion of one mag, I could not discern a difference in follower smoothness between an un-tuned mag and the newly tuned mag. I will get to the range soon to see which mag fouls up first.

[@TANDEMKROSS]

let us know!

[@dennismennerich2666]

Before reassembly I "lube" the follower, plunger, spring and inside of the mag with my silicone impregnated cleaning cloth.

[@TANDEMKROSS]

Great tip! Thanks for sharing :)

[@slandon1977]

I am very happy to come across this video - but it also disappoints me that a pistol from the factory can require so much work to make it reliable. I have a 22/45 that I bought 10 years ago that jams a live round in a stovepipe type position at least once every magazine. I will try these modifications and see if they can fix the issue, but darn - this shouldn't be necessary.

[@Dmurphy527]

Great step by step instructions- thank you.

[@caswinson]

Thankfully I’ve not had the problems others have had and have not had to do this for my guns to function normally.

[@kentuckyjustice1408]

This video helped me a lot. I recently purchased some extra mags for competition, and BOY did they hang and grind! I did as you did in the video, and those things are slicker than owl poop in morning dew. Thanks a lot for this video.

[@TANDEMKROSS]

That's great to hear! Glad you found this helpful :)

[@Dr_Mauser]

What do you do with Mark IV magazines that are not blued but nickel?

[@jnbkay7469]

With all due respects to this great video, the second phase of this modification is not necessary. First of all, the honing of the area said to cause stovepiping is definitely necessary. But doing all that work to the factory follower buttons and slide area is really unnecessary. There is a much simplier route to take - buy and install the VOLQUARTSEN follower buttons. I have replaced 6 of them on my Mark II mags and it was THE CURE. After a quick examination of the VOLQ versus Ruger buttons, you can easily see why they work. Guaranteed ! Save yourself alot of needless work with this part of the upgrade. Otherwise, this is a very good and informative video.

[@TANDEMKROSS]

Thanks for the feedback, James, and thanks for watching!

[@ps2hacker]

Great vid, I was mainly looking to put the follower button on the other side, which worked, btw, but you have given me all kinds of extra improvements. IMO as a right handed, the button is on the wrong side of the magazine, which makes it hard to load.Reversing the follower button has made these SOOOOOO much easier to load, at least for me, anyway. Has anyone else noticed that?

[@TANDEMKROSS]

Thanks for the feedback! Glad you found this helpful.

[@jamesmairs7087]

I had not thought to do that until I read your post. If nothing else glad I watched the vid, 2 of the 6 mags I have stick at the top, and yes the thumb stud would be nicer on the Right side of the mag vs left. Going to take care of that when I get home.

[@terryrambo9981]

I noticed. ..and tried it...worked great but now the bolt does not stay open when empty.. someone needs to make a two-sided button so it's easy to load left or right handed... I put mine back the way it was

[@J.R.F.23]

QUESTION: Do the MK IV pistols benefit from this Magazine Tune-Up as well? Input is especially appreciated from T.K. and or people who have done it to their MK IV pistol magazines.

[@jsigmo]

I have no doubt that the mags that came with my Mk IV 22/45 Lite would benefit greatly from this treatment. They both fail to push the first few rounds (last ones loaded) up because the button binds in its "racetrack". Those top few rounds can just fall out of the magazine after you've loaded it because the follower won't move up, and can't put any spring pressure against them. So I will certainly be smoothing up the follower button and it's racetrack at the very least. The other tuning looks wise, too. Mine feel very gritty and the button sticks when I'm pushing them down or letting them up. I suspect all of them are somewhat like that, so I'd say that yours will benefit to some degree from this treatment. I know mine will. If a guy had a vibratory polisher, as is often used to clean and polish brass casings, and you put the right sort of media in it, that might clean these mag bodies up, too, with little effort. But it would remove all of the bluing, of course. I'm not sure I care about bluing on the mags. I don't want them to rust, but just like with a lot of other parts of these guns, a tiny film of good oil should keep that from happening. It's too bad that Ruger doesn't put a bit more effort into deburring the punched edges of the sheet steel at that point in their manufacturing process. It would likely be a LOT easier for them to do it on the assembly line before the bodies are bent into their final shape. But I guess this gives a lot of us something to do while watching TV when cooped up on a cold, windy, winter day!

[@fokcuk]

Do you need to use a blueing agent? Is it just for the looks?

[@livinnsc]

I just got a Ruger mark 4 22/45 Lite. Ive shot it about 1300 times almost exclusively with silencer. The first 50 shots are fine. After that it starts stovepiping the first rounds on the magazine. I started loading only 5 shots, then it worked flawlessly again. Then i sprayed the magazines with gun oil and it worked flawlessly with full magazines. Spraying them with oil is short term fix as it gathers alot of crap, and also makes for a huge cleaning job afterwards. I was thinking of sending the magazines back to the retailer, but after reading the comments there is a high chance i will get 2 new malfunctioning magazines in return...

[@TANDEMKROSS]

No worries! The Mark III and Mark III 22/45 have different grip dimensions and screw hole layouts. If you have a metal grip frame, grips designed for a Mark III 22/45 or Mark IV 22/45 will not fit.

Not sure why you would polish the retaining plunger because you can’t see it while it’s installed and it does not move while in normal operation. It holds the base plate in place and that’s it.

[@Jaykeev]

Why not...? Is the real question.

[@colinoscopy1438]

I guess so the spring feeds smoothly off the plunger as it extends.

[@galenasomez6059]

most 22/45 mag issues are from the mag riding too low in the handle causing fail to feed

[@Gunners_Mate_Guns]

I'm not going through all this level of work, but I'll probably sand off the tiny bit of flashing on the follower, but it should be mentioned that the current magazines are no longer blued, but are instead stainless, so the bluing is unnecessary.

For me it took about 15 minutes per mag. None of it is difficult. I didn't take much off to round the corners of the rear feed lips but no more stovepipes so it doesn't take much!

[@aowi7280]

Anyone have any tips for the bullet nose hitting the top edge of the chamber? It leaves a dent in the bullet that probably affects accuracy. The mags that I didn't round off the corners don't do this. So I regret doing the mod. And no, I did not round them much at all.

Great video but it would be great if Ruger made some better mags. 2 came with my Mark IV Lite and they both jam every 10 rounds or so.

[@evilvicious]

anybody know if this works with mark iv mags ?

[@korsobalias]

Sure does! The magazines are exactly the same except the basepads.

Good info, thanks!

Just did this process on my 6 magazines (I know only 6 but its a new gun give me a break) for my Mark IV 22/45 target. Pretty simple process took my time and they look good. Now I am just waiting on my blue to cure and my green rocketwire springs to arrive....looking at you TK..... waiting on my springs..... yep just waitin.

2 years later all my magazines are still functioning 100% I have no issues 1000's of rounds later. Thanks again for the great tutorial TK!

Looks like an evening's worth of work per mag but well worth it.
