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.

Fixed it for you.

Fixed it for you.

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