Is the M&P 2.0 10mm reliable?

RenoHuskerDu · Jul 18, 2022

I've seen threads on here about FTFs with the new M&P 2.0 in 10mm. One guy had it largely resolved by sending it back to Smith, where they polished the feed ramp and perhaps other tricks. He says it's much better. Another guy is waiting on his to come back from Smith, last I saw this morning.

I called Smith just now and their position is that it's not a widespread issue so they are handling it on a case by case basis. At least that's the info that Customer Service has. I would like to believe them. I've been hoping Smith would bring out a 10mm M&P for years now.

Is anyone else having feed issues? I'm holding off before I buy one. It would be a backup for pig hunting and those very rare trips into high crime areas. They often push 400 lbs around here and get nasty when wounded.

That seems to be a contentious topic here on the forum. I picked up one a little over a month ago (June 12th), and have shot the heck out of it. Mine’s a 4.6” and from reading the posts, I think the issues are mainly with the 4”. I’ve had some issues with mine, but I think they were more ammo related. Lately I’ve been sticking to 180 grain Berry’s flat point and haven’t had any further problems. It may have been a break-in issue too…I’m at about 1500 rounds and haven’t had any hiccups whatsoever from about 800 rounds forward. I clean pretty regularly and run it well greased with moly grease and worked on the feed ramp some with a garnet scotchbrite pad. My feed ramp had some funky serrations that I didn’t like, so I smoothed them out a bit, but without removing any material. I’m not a fan of polishing feed ramps except as a last resort. I also took the extra step of running my loaded rounds through my vibratory tumbler with some Nu-finish polish for about 20 minutes to get a nice waxy slick coating on them.

So as far as my experience, it’s been mostly positive. I mounted an optic on it and it’s really a hoot to shoot. I have yet to shoot any factory ammo through it, so I can’t address any issues about that.

I am curious if anyone else’s feed ramp has the serrations like mine has. Is it normal or some sort of machining artifact?

that is an ugly feed ramp.

I have had my 4" for about three months so far.

It probably has 800-900 rounds through it, I am not one that really counts such things.

Mos of that ammunition has been my 180 FMJ hand loads that chronograph out of my 1006 at just over 1250. So this is not a powder puff load.

I have run some factory ammunition through it, mostly the Federal 200 JHP and the SIG 180 FMJ and V-Crown but only a few hundred

There were perhaps two or three hiccups early on, but it has been totally reliable for the last 500 rounds or so.

Next time out, I will run some of the heavier ammunition through it. The 220 FMJs and the 240 JHPs.

I have seen a couple of complaints about the Underwood 220 hard cast lead loading. However from the pictures it is the discontinued Underwood 220 load that is giving the problem. Underwood switched to a coated bullet for their 220 grain ammunition. I do not know if that is the issue

I have never shot any Underwood ammunition in my firearms

The feeding problems do not appear to be a design issue, but rather a QA / QC issue. Unfortunately QA and QC add cost, and S&W does not seem to be willing to add that cost.

Until or unless S&W ups their QA / QC game, I can see only three choices for those wanting a 10mm M&P:

1) Accept the possibility you might have to invest additional time and/or money into getting your M&P 10mm to be reliable.

2) Hope you're lucky enough to get one that works perfectly from the factory - the odds appear to be in your favor. But be prepared to return or sell if you are unlucky.

3) Choose another brand of 10mm pistol with better QA / QC, but higher initial cost.

All of this is just my opinion, and YMMV.

I have 4.6 100% reliable with all types of ammo. My most common round is 165 grain RNFP target load. Very happy with the gun..

If you want an absolutely reliable 10 mm get a revolver. 10 mm loads vary so widely in bullet weight and power it's asking a lot of a semi to shoot whatever you put in it 100%. Mostly I think, it's getting the spring strength exactly right for your preferred loading.

The time-tested G20 is a solid option. One of my boys carries one. If Smith doesn't sort out QC on this 10mm, I just might go Glock again. Did for 20+ years, competed with a G35, carried a G27. Zero issues, even after "race Glock" trigger jobs.

As for revolver, I agree. My backup is an SP101. Only a revolver will absolutely positively go bang every time. Even if pressed into a perp who has me down.

4.6" here. No issues with the new normal power (downloaded) factory ammo and OEM recoil spring. With the hot stuff I needed a $10 Glock 24# recoil spring. With the 24# spring she will feed anything.

FWIW I tried a 22# spring first and it wasn't 100% with the heavy thumper loads.

I bought a new m&p 10mm 4.6 back in May. The good news is that it has fed any and all ammo that I have used without any failures to feed or eject. I use mostly 180 grain loads. Now for the bad news: after about 300 rounds, the pistol started ejecting the magazine during firing! The first time this happened I thought I might have hit the mag release button accidentally, but then it happened two more times. I made certain that my fingers were no where near the mag release the last two times this happened. This occurred with the two separate magazines that came with the pistol. I have contacted S&W about this and I am waiting for their reply. By contrast, I have a Springfield Armory XDM 10mm that has gone through at least a thousand full power loads with no issues at all. I really love M&P pistols and I am quite disappointed by this. I hope that S&W will make this right….

You must have missed the thread linked below, one of the biggest to have appeared recently in the M&P Semi-Auto section. Based on what the OP experienced, don't get your hopes up.

Problem with M&P 10mm + Customer Service Nightmare

Will the Wolff springs made for the 45ACP M&P not work?

Seems like it might be a good idea to have two sets of recoil springs and guide rods. One would be for anemic factory loads and the other would be for the hotter loads.

M29since14 · Jul 21, 2022

I’ve had a bunch of 10mm brass lying around since the Delta Elite days. Some of it is pretty well used. Being cheap, I’ve shot way more of my handloads through my 4.6” gun than I have factory loads. I’ve had zero failures to feed, or any other failures, for that matter. I’d buy another one tomorrow if I thought I needed it. My only complaint is that S&W doesn’t offer one with standard height sights. If you want to put on a reflex type sight, you’re all set to go. I’m giving that some thought.

I have this guide rod and spring, I have replaced the original captive that came with the gun. It works fine and seems to be a stiffer spring. It handles my light target reloads with no issues.

Please contact S&W about this, even though (based on my experience) they may not actually solve the problem. Sooner or later, they'll have to acknowledge the pistol's design flaw(s). Tons of people are reporting the mag ejection problem.

IMHO a flat wire spring is superior to a round wire spring (flat wire lasts way longer), so I'm unsure why anyone would want to go to a Wolff spring. I say this with many years of 1911 competition experience where I was continually changing the recoil spring. Flat wire Glock springs of various weights are widely available.

I shot mine for the first time yesterday at about seven yards.

I started off with 50rds of S&B 180gr FMJ. It was definitely more stout than my 9mm M&P, but not too bad. Accuracy was excellent and it was 100% reliable. When I dry fired it previously, I thought the trigger was going to be sub par, but it was actually quite good during live fire. Here's the first group of 15.

I then fired 50rds of reloaded Zero 180gr JHP's over 10.0gr AA#7. This load felt a little hotter than the S&B factory load. Again, it was accurate and 100% reliable. My only complaint if I had to have one is that the grips are a little too aggressive. Here's the first group of 15.

I'm very pleased so far and crossing my fingers that any issues don't arise in the future.

First outing with my 4" was not promising. Consistent failure to feed the second to last round in the magazine. Did not matter what type of ammunition or how many rounds were loaded in the magazine. 50% of the time the last round in the magazine would jam vertically between the breech face of the slide and hood of the barrel, again did not matter what ammo was being used. Consistently low point of impact, bottom edge of the paper at 10 yards and not even on paper at 20 yards. Had an instructor at the club try it with the same results.

I've got an e-mail into Smith requesting a warranty return, we'll see how it goes.

J10mm · Jul 27, 2022

No issues with my 4.6" 10mm M&P. I've been running full load 180gr bullets in my range trips. Loaded some 200gr "full loads" for the next range trip. I have not run 220gr bullets through the M&P, my Delta Elite or previously owned S&W 610 revolvers. Seems like jacketed bullets cap at 200gr until I'm missing some obsolete manufacturer.

larbike · Jul 28, 2022

My M&P is on it’s way back to S&W. I’ll let you all know how it works out……..

Is the M&P 2.0 10mm reliable?
