Full NP3+ treatment on a P-35; everything but the bore interior. I call it the obama/hillary special. Robar did discover that the hammer was following the slide and it required a trigger job. But I was told it would be an additional week with expected completion on 8/8. I guess I just need to wait.

If you need mags the best place to buy them is Botach when they have a sale. I get S&W mags for near $20 per from them but you need to jump on them as they sell out fast. Yeah Pro-mags have a terrible rep' and for $20 for S&W mags from Botach it's just not worth buying junk.

I have no doubt that you'll figure it out.

You'll be very happy with Robar's work! I bet that trigger job will be sweet!

THANKS for the tip on the place to buy mags. Just bookmarked it.

Spent time yesterday really examining the magazine and how they seated in the grip. Calipers reveal the Promag sits noticeably lower and I think the real problem is, looser, in the grip. So when under pressure from my lower fingers it tilts inside the grip bringing the rounds down JUST enough to hit the bottom of the barrel. So, that seems to be the culprit so far. Waiting for new mag to test.

THANKS!

I didn't criticize anyone, actually I think it was quite the other way around (look in mirror sir), I was just honestly asking for help and good ideas. Wasn't really looking for folks to just be nasty. But, if that's your thing ok.

So, "putz", "stupidity", and because of where I live you have fairly judged me....

Ok, thanks for the input, now back to actually trying to solve a problem. Have a great day and feel great you flamed someone you don't even know...

Anyway, thanks to the folks that are actually trying to help.

Just a my $.02 about MP9Werks. He isn't "that guy". He has helped me and many others on this forum for years with his expert advice. He is one of the more knowledgeable members we have in terms of gunsmithing our M&P's if he has the necessary information in order to diagnose.

Other people have been offering help also, and maybe as perplexed as I am with the issue you're experiencing.

Welcome to the group!

I did take your comments about the lack of replies as condescending. Would I have worded as bluntly as MP9Werks, no.

This perception was further reinforced by pointing out replies, such as this one, were not worthy.

I can tell you even from my limited time here, MP9Werks has given solid advice.

You have every right to behave or say how you feel (within moderator reason). Others have the right to scroll by without offering advice or pointing out your approach might not be the best.

I hope your FTF issue gets resolved!

Stay Safe!

I agree with you as well! At first I read it as someone ticked he did not get alot of replies right away! BUT I do understand hid frustration in having a problem he would like to resolve right away! It is hard to read the tone of a post vs talking face to face and know how someone really wanted to say it! BUT always good advice will show up here sooner or later and so far alot of good advice with 1 minor glitch lol

mp9werks sells or did sell Anatomy Series Manuals for the M&P, and also the The M&P Appendix Manual. They are very detailed and illustrated.

I bought both and refer to them quite often.

Yup, lots of times we're just as perplexed as the person posting a problem. We just won't post if we can't offer a solution. Who needs to read, "Gee that sux!". You already knew that or you wouldn't post and that lack of response might make it appear that no one cares. That just isn't the case.

I'm betting ditching the ProMag will solve the problem from the sound of it. I considered going that route also to "save money" until someone on our local competition website clued me in about Botach. I haven't gotten a dud S&W mag yet and I've bought my share. :-) Maybe more than my share.

I'm staying tuned in to find out.

BTW, if you're serious about a handgun, especially in this political climate, I consider 10 mags to be entry level. Without functioning mags you just have a very slow to shoot single shot. Some rebuild kits or replacement springs aren't a bad idea either.

OK, since it's a ProMag and you have a proper mag coming in, you have nothing to lose. I'd bend the lips a bit to make them right (if that's even possible). Look at what's happening and modify the mag as required. I've been known to grind away lips to make mags work with certain ammo. (semi wadcutters in a 1911) If you make it work I'd put it in the "working, but not for serious use" mag' bin. There's no way I'd ever trust it again; it's just not worth it.

Thanks everyone!

First, it sure wasn't the lack, or lack of speed reply's that caused any frustrations. Believe me I'm in it for the long haul to solve things. I never expected quick and complete resolution. What bugged me was no offer of ideas and folks just immediately implying that my choices of mods were "stupidity" etc... I really appreciate the great ideas that HAVE come from here. so thanks again to the positive folks.

Honestly, I carry a tried and true 1911 as my CCW. But this has been fun project gun for lots of things I always wanted to try. Having folks get bent about doing those modifications was just really uncomfortable, when I came to what I thought was a supportive forum to try ans solve a bit of a mystery.

Glad the aforementioned gent has helped others, but the name calling was uncalled for, and as others point out, I guess I should just ignore it and carry on! Anyway, I have found so many of you other folks to be VERY helpful and I am very grateful for the interest!

I am more convinced as time goes by it is the mag, perhaps with a combo of the ammo...? But the calipers don't lie when it says the 'ProMag' is hanging lower int he magwell and would lead to the bullet not being carried far enough up into the feed ramp. Testing the S&W Mag as soon as I get and thanks to BrainK for the tip on Botach site for great mag prices.

It isn't that your various mods were "stupid."

It's the simple fact that when anyone makes multiple mods to a pistol; it makes it much harder to determine just what's causing the problem, especially (as I noted) when you can't examine the pistol personally to see/feel what's going on.

If it were mine, I'd start by putting it back to stock (I know you can't completely with the refinishing), then reinstalling the various aftermarket parts until I hit the one causing the problem.

As a 1911 guy (I am, too) you probably understand which parts are most likely related to FTF, FTE, FTRB, and other issues. Some of that knowledge carries over to the M&P platform. The rest you'll come to understand as you become more familiar with the M&P.

That said, very little hand fitting is required to make/keep an M&P running, when changing components; compared to a 1911. The M&P is much more "plug and play," like an AR.

So...

Received the S&W 15 rd mag today. Off to the range. Fired 200 rounds. Only ONE FTF. I think it was because it accidentally bumped the mag release during .357 sig recoil.

It performed flawlessly (even with all the silly mods

Slow fire, double taps. Mag dump. all went great. Caliper comparison agrees with all of you good folks that apparently Promag makes crap... (see photos)

I wrote their support with the pics just to see what they say.

Thanks again for all the positive replies!

That's good news! Now take your old mags & strip them & clean them but before doing that look closly at the top of the mag comparing the opening to the factory stock mag. Check for any burrs or roughness. I have a hunch (just a hunch mind you) that the combination of mags & ammo might just be the problem. The tolerances might not match just right.

I think you are exactly right.

I looked with magnification at the aftermarket mag, but no roughness or burrs. But as you see in the pics the tolerances are sure off from the factory mag! So, I think if I ran full rounded bullets in the Promag it may work, but as you say the combo of the semi blunt reloads with the poor tolerance led to failure.

The S&W mag seems to take care of the problem! Still waiting for a reply from Promag Customer Support.

THANKS!!!
