S&W M&P 10mm FTF Fixed? Lets Test It! Part 1

[@warmothgmc]

What is the factory spring on the 4.6” version? I’ve been experiencing some FTF’s with even S&B 180gr FMJ, which is a pretty tame round. It has been getting a little better the more rounds I put through it. For a while, it was really bad. It would stove pipe on literally every round. I managed to get through a full mag of the S&B the last time I took it out. I’ve also been hearing some of it could be related to the factory mag springs. Seems Spencer Precision Extra Power mag springs has helped improve the reliability in conjunction with maybe a Wolfe recoil spring in the 20 to 22lb range.

I'm assuming its also a 17lb spring. how many rounds have you put through the gun? still might be in the break in period, but shouldn't have these kind of issues from the factory IMO. I have the stiffer mag springs which didn't help. I have the 24lb recoil spring installed, but haven't tested it yet. maybe tomorrow. if that does not work i will try the 26lb spring as a last resort and if that does not work i'm not sure what ill do with it. maybe shoot it with my Barrett lol.

Do you have a link to the 24lb spring? I couldn't find it on their website. I just got the performance center version and had a bunch of failures to feed on my first 100 rounds. First semi-auto I've bought that had FTF issues right out of the box, unacceptable!

@@markkepley4131 shop.springerprecision.com/m-p-recoil-spring/ FTF issues is unacceptable out of the box. I still have yet to try the 24-26lb spring, but I’m leaning more towards getting the 26lb spring over the 24lb. And really I only had problems with the hsm bear loads. The underwood ran perfectly, but that was only one mag. Everything else ran perfect as well where with the factory spring I was having all sorts of FTF’s and it didn’t matter ammo I was running. Hope this helps!

@@CabinPews Thank you. Did you keep the original guide rod or buy one from Galloway?

I put a 24lb spring in mine and it made very little difference i have magazine springs on the way hopefully it fixes it.

[@CabinPews]

@@dylanbrown3840 what ammo are you running? What’s your barrel length?

[@dylanbrown3840]

@CabinPews it's a 4 inch and I just bought it and have only ran two different kinds of ammo. I ran 100 rounds of speer 180 grain and 20 rounds of 200 grain hardcast bear ammo. The 24lb spring definitely improved the reliability of the 180 grain.

[@CabinPews]

@@dylanbrown3840 copy that. What brand for the 200gr hard cast? I noticed I only had issues with the HSM ammo. Everything else seemed to function fine with a 22lb spring. I have the 24lb spring installed In the gun, but have yet to try it.

[@dylanbrown3840]

@CabinPews it's called Velo its from sportsman warehouse I'm going to try some different one when my mag springs come in

[@CabinPews]

@@dylanbrown3840try some underwood. Haven’t had a problem with them yet

[@BubuPoons]

I ran into this problem myself but haven’t gotten around to fixing it. I’ll try this out!

[@CabinPews]

Let me know how it goes!

[@BubuPoons]

@@CabinPews just tested today, worked for me also. This helped a lot

[@CabinPews]

@@BubuPoons sweet! I have a 24lb spring I’m going to try and I’ll put out a new vid this weekend and see if it works even better.

[@rox3725]

The feed lips onn the magazine seem too short.

[@CabinPews]

Yeah I was thinking that as well.

[@modakkagitplugga]

The galloway 24 lbs recoil spring seemed to help my 4.6", but moving away from isocoles and locking my right arm out seemed to be the best combo for relability. I still have initial feeding issues from the first round out of a fresh magazine, so I'm going to try replacing the magazine springs with some springer precision and then polish the feed ramp with a compressed cotton dremel bit and some green vert jewelers polish. If i'm still running into issues, I'm trading it in for a shield plus. I like the extra horsepower to match .357 magnum, but at the end of the day only reliable firearms are worth carrying

[@CabinPews]

I have the Galloway 24lb spring in my hands now, just need to try it out. I’ve noticed that I really only had issues with the HSM bear loads. All other factory ammo cycled fine when I added the 22lb spring. I’m curious if the Galloway spring will help. When I added the springer mag springs the improvement was marginal and I still had the same issues and if anything it made it worse. At least on my 4” model. A polish can’t hurt, but we shouldn’t have to do this lol. I might end up going with FN 510 instead of this thing. Only problem with that gun is I have massive hands, so slide bite is inevitable.
