Problem with M&P 10mm + Customer Service Nightmare

Then we find video's of guys that find the fix and have no mag related issues . Just recoil springs . Glock20 ismi springs . I've been running them for years now in a m&p core shooting 9mm major loads and have change to heavier ism springs in a m&p 4" compact 4.35 40 and 5" 2.0 as there all under sprung for hot loads . Plenty of room to compress a longer flat wire spring in the compact 4" 10mm . Just try heavier ISMI recoil springs . If you won't try thats your fault . The pistol was not designed to shoot extra hot non-saami ammo with our some help . Funny tread common sense is gone from some folks here .
Heres real owners that figure it out .

Every single round I fired, and every single round that induced the mag drop, was SAAMI-spec.

It's not my job to attempt to compensate for flaws in S&W's design and/or manufacturing with aftermarket parts that may or may not actually solve the problem.

Looking forward to trying the Sig.

mark mark mark More excuses and whine from you . Glad your finally moving on to anything else so guys that buy the m&p 10mm can get on with enjoying them . Hope Sig has chamber are in spec . Blow or deformed brass has been a 9mm issue with sig for a year or two . So your movie from a 4" to a 5" 33oz pistol that 5.6": tall too . Yea , that makes since . Ha Bye Bye

4.6" to 5", actually. And I'm actually a fan of the additional barrel length, so that's a plus.

But that's neither here nor there.

I've been entirely respectful to everyone--including S&W personnel--throughout this process, and I've been careful to document everything, test thoroughly and with all due diligence, etc. I've been as clear as I can possibly be when explaining things in writing, despite the fact that what I write is not always read carefully.

Your antipathy toward me is very bizarre and unnecessary. I'm an adult -- I'll survive. Still, I hope you'll treat the next guy who has a bad experience with more respect than you've shown me.

You've had quite an unfortunate experience and I don't blame you at all for the attitude that the pistol should work correctly right out of the box. It seems like the frame might be flexing under top end loads and a heavier recoil spring could be the work-around. Even then, I wonder what 5K rounds would do to a gun equipped with the heavier recoil spring?

For me , when I finally scratch that 10mm itch, it'll be a metal framed gun. Polymer may have met it's match with full house 10mm.
 
Only problem I've had with my M&P 10mm has been with brass thrown 18' to 20' to right rear on about a 45 degree angle from me. I a first thought it was due to weak recoil spring. But having the same result for case travel even with loads down light to almost not working the slide. So that means only one thing and that's the ejector is the cause. I would like to put a trigger pull gage to the slide and just see what the gage reads, but I have no trigger gage and I ain't buying one either.

As for magazine it's excellent design and functions 100% of the time except when I fail to tap magazine back on my palm or on the deck rail.

I would not carry this size and weight of gun in 10mm except as a woods emergency gun and even then, I would rather have my 1911 Dan Wesson RZ10 with 22lb hammer and recoil springs. It's easy to shoot with no God-awful recoil and accurate like a match gun. I like the other M&P's we have but this one I not sure of as yet. I bought to carry in car, but the old CZ 75 CS 9mm will say put with Underwood solid copper bullets for now.
 
Very discouraging. It seems as if most, if not all, of S&W's M&P polymer models have had problems with mags ejecting during firing, if the posts and threads on this site are to be believed. Such a pistol does not inspire confidence.

Most of the M&P line has had problems with mags ejecting? This 10mm post by @mark_lives_things was the 1st I've heard of this happening.

I don't know if it's "most," but there are definitely a lot of people experiencing the same problem. There are a few others who I've mentioned in this thread, many others I've come across later on. In addition to those I've noted in this thread, look at the comments on the first video and the content of the second video here:

Oh yea I'm aware of the 10mm issues, but i was referring to the M&P 2.0 9mm variants. Thanks for the links.
 
I believe this issue is only with 10mm pistols, none of the other variants have had reports of mag ejection.

I'll be trying some Underwood 220gr hard cast & 200gr XTP in my 4" M&P 2.0 10mm on Friday, crossing my fingers. :D
