💥10mm VS .357 Magnum💥 Episode 8. Underwood HARD Cast

[@GunSam]

VERY IMPORTANT, read this before you watch! I get the "limp wrist" comment nearly daily in one video or another with this pistol, but from people who haven't a clue what they are talking about, so I urge you not to jump to conclusions. Most of the issue with malfunctions is the feed ramp, the Lone Wolf AlphaWolf CONVERSION barrel I use has a very thin feed ramp, not wide and loose chamber like a stock Glock feed ramp/chamber. Also, in this video I was not using a 10mm extractor in the conversion, so that didn't help. If you still do not believe me, I did a study of all of the hollow point ammo tests I did with this Glock 41 pistol in both the stock and the conversion setup. Why this is important is because I tested SEVERAL .45 ACP+P rounds that were well over the typical energy level of 10mm, as well as at or above typical 10mm bullet weight, and I never once had a jam in those rounds. Here is the study of just the Glock 41 portion: Glock 41 (.45 ACP) Shots Fired: 93 Malfunctions: 1 Malfunction Rate: 1.1% Glock 41 (10mm Conversion) Shots Fired: 102 Malfunctions: 23 Malfunction Rate: 22.5%

With some brand types, you might get better accuracy or smaller groups, but they all go bang.

[@GunSam]

Typically yes, BUT...I have had some really bad revolver ammo that was so incredibly dirty it sooted up the breech face to the point of jamming rotation.

Yep, everything works just fine as long as it’s not too long for the cylinder. Some loads will obviously give better results than others, but all will give a result.

[@GeographyCzar]

Gun Sam, your tests are absolutely crucial to the modern revolver-o-phile. Thank you!

[@GunSam]

Thank you. Same with yours. It's awesome to see different mediums. I think ultimately what is most valid is to take the rounds that have a proven track record like the 125 gr .357 Mag SJHP at 1,450 FPS, see what that does in any repeatable medium, and then compare everything else to that. One could use nothing but wet phone books and you would learn from it. So it's fun to just compare everything based on something else. Almost just thought of a video series while typing now lol. Find a large supply of Federal, Winchester or Remington 125 gr SJHP and do a test where whatever is tested is compared to that. That would be cool to see, as that round is still the standard.

@ Al Shoenbeck, With all due respect to Sam here, he runs a Glock 41 (.45 auto) with a lone wolf conversion. If he had a g20, highly doubtful he would have these issues. I own a g20 and do not experience these malfunctions. Any to date actually and have owned it since 2012.

[@scubaguy007]

Very impressive demonstration. 10mm is on top in this video for sure. I wonder if that .357 round was tested with a 6" barrel. That seems to be a more popular for hunting. I checked their website but didn’t see anything about it. Thank for what you do, it keeps me thinking.

[@johnnyvasquez4605]

Ive actually emailed them before and they told me they use a 6" for all 357 tests. So their listed velocities are based on that, not a 4". I wish they would test in a 4" though.

[@GunSam]

Yes, Underwood has also said 6" to me. But what really bugs me is that Underwood copies Buffalo Bore specs, and Buffalo Bore .357 Mag gave me 1,388 FPS or something like that. Same "1,400 FPS" on the box. But again, the numbers I see when researching 6" .357 Mag velocities are typically like 50 FPS above 4", so even in a 6" i'd probably have gotten 1,250 FPS, a far cry from 1,400 FPS. As Paul Harrell might say, Underwood is "optimistic" with their ratings.

[@adamlowe9532]

Hey. Got some info I would like to share on the 41 with the route I took with mine. Probably too much to share on here. Mine has always been a reliable tack driver. Hit 3 inches high, so I went with a slightly taller fiber optic sight. One the conversion end of it, and I run 10mm and 45 super, I got a gen 3 wide stainless extended alpha wolf slide. Got an uncaptive wolff guide rod and a 20, 22, and 24 lb spring. With my hand loads I have to run at least a 22 lb spring with the 10mm. But the 24 is pretty sweet with the heat I'm delivering with hand loads in 10 mm and 45 super. Both my barrels are storm lake 6in. No threads, no ports. They are for a 21. Wide slide. Believe it or not in running a factory 45 extractor and have had great luck with it. The barrel you have has the thinner contour for the narrow slide. Not sure if there is possibly a timing issue with its weight or you could maybe get a gen 4 to gen 3 conversion plug to get an uncaptive spring setup like I mentioned to tune the slide to different loads.

[@GunSam]

I have noticed that some ammo ran fine with the .45 extractor and some not. The SAAMI spec for rim thickness on .45 Auto is .049" and for 10mm .055". I decided to measure the rims of the ammo I tested in 10mm running the .45 extractor and they were all basically thin for spec, 10mm rims at .049" and .050". I did try to file the little nub on the .45 extractor but never was able to, but the 10mm extractor has cleared up some of the issues. For me it's a mess as sometimes the jams were the extractor sometimes not, other times the magazine other times not and sometimes the chamber and other times not. What I can say is that now currently, it runs relatively okay with low-mid range power ammo that has rounded HP noses. My spring in a NDZ 22 lb.

[@donaldballman2825]

That's why I like revolvers you don't have feed issues don't get me wrong auto's hold more rounds in most cases but what good is a firearm that keeps jamming

[@Predalien195]

Have you changed out the recoil spring a guide rod assembly on that Glock? Because full house 10mm like that can malfunction bad if you haven't. The stock 17lb spring isn't good for it but also far less comfortable and controllable. Correct me if I'm wrong but isn't your Glock also a conversion from a G21?

[@GunSam]

It is a G41 and has an NDZ 22 lbs spring and guide rod assembly.

[@AlaskanBallistics]

Convert your .45 acp glock to .45 super instead of 10mm...is it still the factory recoil spring?

[@GunSam]

I had thought about it, because it's a .22 lb recoil spring. All i'd need is a match .45 ACP barrel if i'm not mistaken.

[@lutherpayne9957]

Most likely the conversion barrel. Chambers tend to be tighter tolerances. Good presentation.

[@GunSam]

Yes this is also my takeaway of the situation. Everything is setup to work fine, and it does work fine with all round profile hollow points. I have inspected the stock Glock style chamber to this conversion barrel and it's not even close. There's no relief or anything.

[@roberta6360]

What spring weight do you have in the Glock? Have you tried a different spring weight to solve the jamming problem? Just curious. Great video.

[@GunSam]

22 lb and the stock. I have tried both. For the most part the stock 17 lb works better for low end rounds. The heavier one decreases reliability but is needed for hot rounds.

[@addytuney2028]

Hello Sam and thank you! I am curious if you know someone with a glock 20 where they would let you try their barrel in your glock 21. I say this because i noticed the conversion barrel i have for my glock 20 (40s&w conversion) has a decently polished ramp but the entrance to the chamber does not have the sharp edges contoured like the factory g20 barrel. Also under the hood is polished in my factory barrel but not the conversion. You seem pretty handy and you most likely have a dremel, maybe if you slightly contour then polish those sharp edges it might function better.

[@GunSam]

Maybe. And it's a Glock 41.

[@josephmeador1529]

12:00 There is an interesting phenomenon that occurs in .357 ballistics for some rounds. The bullet velocities will increase in relation to barrel length until you hit the 6 in barrel ... a lot of .357 will go slower out of a 6 inch barrel than a 5 inch barrel or a 7 in barrel. In other words you could get 1000 ft/s at 5 inches, 900 ft/s at 6 inches , then 1100 ft/s at 7 inches. The velocities on a graph actually DIP at 6 inches.

[@williammcconnell9501]

First, let me thank you for all your testing and your testing methods. What you do tells a story that ballistic gel does not tell. Both are analogs for what really happens when a bullet hits meat & bone. I like yours better but that is certainly a matter of opinion. I ran into similar problems to your 10mm conversion with my 10mm G29. Like you it is when shooting the nuclear stuff that delivers the highest slide velocity. You have a fairly light 45 acp slide so, all things being equal, your slide velocity is greater than my G20. According to Glock your gun is 4 oz lighter than my G20. Most of that is in the slide. You put in a 22# recoil spring just as I did in the G29. But it did not solve all the problems. Ask yourself this.... if you hold the gun super tight when shooting it, does the slide velocity become greater or less? IME the slide just goes faster since there is more resistance to holding the gun still. I had fewer of those nose up jams when shooting the G29 one handed. The solution for me was to get a few Wolff +10% mag springs for the G29. The problem went away instantly. The problem was the OEM mag spring could not lift the cartridge up to the feed lips fast enough to deal with the higher slide velocity. I do not know all that may be wrong with your G41 but suspect much of the problem with the nuclear loads is the same problem I had with the light slide on my G29.

[@GunSam]

I tested everything, every method etc. With the current setup it's about 90% reliable with JHP ammo and 20% reliable with flat nose ammo. So I think it's mostly the chamber.

And I do agree. I feel like any single stack 10mm with some weight behind, all steel it makes more sense. Like, making a polymer pistol in 10mm seems sort of dumb. Sure it fires when it has a good grip on it, but the intended purpose is for bear defense, which does not really mash well with the theory of using 10mm. It's like "hey lets make a 10mm that's for bear defense for a guy to use after he just ran and fell down a hill running from a bear, and make it so when he uses his weak arm which will probably happen at some point, make it jam every shot".

Thanks. That's my impression too. The hottest round I tested in this pistol in 10mm was 792 ft lbs energy, and for .357 the hottest in this revolver was 794 ft lbs energy, and both of those numbers are like the max, so it's safe to say they are equal in power. Both have loads that can either be used for self defense or hunting, but in general i'd say the 10mm is a little more suitable for hunting as it's bullet weights typically start at 180 gr, and the .357 Mag is a little more suitable for self defense with the bullets typically starting at 125 gr. But again, you could go uncommon weight for caliber and swap up it's use.

I don't trust Underwood. Their velocities never seem true. Their heavy 38+p round seems like a good one, but i will take Buffalo Bore before Underwood. If i were you, i would abandon the conversion and het a dedicated 10mm gun- Maybe an XDM 5.25" (or a GP100!). You wr ill probably be better off. As it is, 10 mm conversion is only good for anmo tests- you can't trust it in the field or for hone defense. That is too bad, too, since you have invested the money

[@GunSam]

I guess for me the thing is, I do not need a 10mm or want one. I just got the conversion setup to test ammo.

Friends don’t tell friends to buy Glocks; there are better options.

[@kirkhiggins3044]

Have your cake and eat it too. Get a 10mm GP100.

[@GunSam]

If I did something like that, I would get a S&W because across the board S&W tends to shoot faster than Ruger revolvers.

[@troy9477]

Exactly! That is my plan- get the GP100 in 10mm.

Ok great video as always. Biggest discrepancy is weight and size of projectiles. 357 diameter can vary cast to jacketed but usually 0.357 to 0.359 and 10mm usually 0.400 in all load data I have on the round. 40 grain difference in projectile weight and lets say 0.040 in diameter variation. Now a closer comparison in my eyes. If you want a od with acceptable variances lets get to a closer comparison 41mag. Now we have identical projectile weights. Now we have a 0.410 diameter in a 41mag now in the closest caliber comparison the 10mm shows no comparison with the 41 mag. Now for the auto guys take the Desert Eagle 50ae and a Ruger Alaskan in 480 almost identical ballistics. See which one you can put in your pocket ? Now my 500 is pretty awesome. But back to defense weapons I like dancing beer cans as much as any kind of shooting I ever done.

GLOCK

[@russelder9743]

I had a Glock 22 and it would jam every time I shot my re-loads it shoot store ammo fine...my reloads shot fine in other pistols just not that G22...I traded it towards a Ruger 1911....stay safe buddy

[@GunSam]

Thank you, you too.

[@chrisgabbert658]

It looks like you have a bad Glock. I personally don’t care for them but I like medal and wood that’s just me.

[@poorfatman5317]

Once again The Revolver far more reliable
