M&P jamming while chambering a round

My own experience is based on 10+ different (including 3 of my own) M&P9’s (4.25" fullsize) with 15 of my own magazines and every other magazine from the other owners/officers pistols over the past 4 years.

Additionally, I have replicated the “Auto forwarding”/failure to feed issue with several different defensive loads. I have also replicated it with a KKM match barrel and the different defensive loads. It is not specific to my 3 pistols, or the several other M&P9’s that I have handled. I am confident I can replicate the same with ANY M&P9 fullsize that is handed to me.

I have done the testing based off of my training experience with the platform, and I am comfortable carrying the platform and use either the slide stop or the over the top method to send the slide into battery during loading, emergency reloads etc. I avoid employing the “auto forward” technique for all of my pistol platforms.

I could make the ftf issue occur at-will with any of the pistols I have handled. The failure to chamber issue shown in the video I posted is a new issue reserved for that specific pistol and all of its new style mags.

I believe KhanRad is spot-on regarding the need for an extended feedramp on the 9mm M&P’s.

Hi all -

I’ve researched for months to decide on my best CCW option, decided to go w/M&P due primarily to info on this forum (ergonomics, accuracy, reliability, on and on), decided to go w/9mm (after years of “bigger is better”) for many reasons (shooting cost, hi-cap, essentially same effectiveness, less recoil, on and on) espoused on several forums - and then I read the above thread/post.

This seems a big problem, given the emphasis on reliability as, perhaps arguably, Item 1 on most everyone’s what-to-buy checklist.

Right now, I don’t want (having to decide on) another make or caliber, so I ask all to refrain from such suggestions at this point.

So what’s the “rest of the story” on this issue?
Is this only when “auto-forwarding” or have I made a bad decision?

Thanks.

regards,

I agree with member nickdrak that I can replicate a failure to feed consistently with the new square base plate magazines. My circle base plate magazines are still 100%(when tested with FMJ and Winchester Ranger T RA9TA).
To be honest, I’d bet it is ammo specific and if I could get my hands on some Federal HST or Speer Gold Dots I’d like to test it a bit more.

I think I read in the “M&P Problems” thread that the 9mm has probs feeding mid-weight HPs, which is what I understand to be most recommended and what I’d want to shoot.

Another [u]big[u] prob for me if it’s endemic.

JW -Not getting any info so far, but I’m not familiar w/the mags.
If it’s better feeding, is the circular style available separately?

Thanks.

Well, shit. This is the first Ive heard of this problem.

Apparently it’s not just from auto-forwarding, but it’s sure a deal-breaker for me if it’s common to the 9mms.

Mine alway auto forwards when I 45 Degree Bump it…I like that feature and have never had a problem with either style of mag.

8

Fixed it for you.

Not a design flaw…especially when you consider the same can be done with Glocks, Berettas, and some Sigs.

10

… and HKs.

The question is:
Should one trust one’s life to a SD handgun that may or may not feed SD HP ammo during loading (and even emergency (tactical?) reloading, as one poster reported)?

Yes, any machine can fail, but seems the M&P9 is fine for folks willing to make it right (as the .45 Gov’t-style is often characterized these days).

I’m still reading thru 34 pages of the “Problem” thread and feel more and more that the M&P9 is not the right choice for me.
Guess I need to decide between Glock 9mm or M&P40.

regards,

Here’s what Jason Falla says on the topic…

Sorry if i missed it but could this be a NEW M&P??

I know over at the M&P pistol forum (hope i didn’t break any rules)
it is commonly talked about that there is a small “break-in” to these pistols before Hollow Points load 100%

shoot a few hundred FMJ’s and even put a little polish to the feed ramp
then move to JHP or other Hollow Points.

(if it is a new mag issue sorry I’ve been out of the loop as i have 7 rounded gray followers mags and had ZERO issue after the “FMJ Break-In”)

14

Uh oh guys, M&Ps are totally worthless! And now so are Glocks too! and SIGs!! and any 1911 that didnt cost 8,000 dollars!!

I’m going to give up shooting all together and practice my kung-fu…

15

I’ll restate my concern:

I want one, but it seems there may be a design flaw in the 9mm M&Ps, possibly caused by a short feedramp, which causes 9mm JHPs, including the +P loads recommended by S&W for these models, to not feed reliably.
It is appparently not a magazine issue (beyond the fact that mags are not designed secifically for the tapered 9mm case), but likely due to the original .40 cal. feedramp design being used for the 9mm, which, due to tapered-case design, does not have the same feed characteristics/mechanics as either .40 or .45 straight-walled cases.

nickdrak noted: “I could make the ftf issue occur at-will with any of the pistols I have handled.”
If true, this disqualifies the 9mms as a self-defense handgun for me, no matter how well they shoot FMJ practice ammo.

And I’ll ask 2 simple questions:

If you have shot JHP in your M&P9, has jamming been a problem with them?
If so, does power-stroking cure the problem?

Personal experience input will be greatly appreciated.

Thanks.

Over 5K with my 9FS all with 124gr HPs and I have not not had one problem. Never any ball ammo. No break in period. No FTF & no FTE. Ammo is mostly my reloads and Speer 124+P. I never auto-forward. It will if I try, but I consider it a unsafe practice. Of course, now it will go all to hell on my next trip to the range.:smiley:

17

I have never tried this with an HK. This happens all the time with my Glock. I’m not sure how to feel about it. I would hate to rely on it though and have it NOT happen in a moment when you expect it to.

As far as the 9mm mp being messed up. This is also the first time I have read this and it makes me wonder since I was planning on picking one up.:smiley:

18

I think most any semi-auto, light-framed maybe easier than heavy, will autoforward if slapped hard enough with a full mag - just the physics of mag inertia overcoming tension on the slide stop/release and of no real concern to me, tho’ I’d also much rather have it one or the other.

But a pistol for SD possibly not feeding SD ammo is a biggie.

DJK - glad to hear your positive experience and best of luck next time out. :wink:

19

You concern isn’t warranted. Remember that we are talking about a IMPROPER emergency reload. No, auto-forwarding is NOT the proper way to load the gun and is why it is NOT a valid technique or something that should EVER be taught or practiced.

The M&P DOES feed SD ammo (when the weapon is properly fed).
