45 FS FTF and fire

[GT1]

About 300 rounds of factory ammo through my M&P .45. Like the feel and it shoots way better than me.

I ran 2 100 boxes of WWB through the pistol and had 4 failures to feed in that time(various mags). I am now shooting Rem UMC target which is nice ammo. I had a failure to fire today, the round was in battery, but the striker no clicky, no nothing. This is about 100 rounds into the Rem ammo which has been flawless up to then. A couple more mags after went fine.

The pistol had a decent cleaning for the first time a couple days ago.

I like the pistol and would like to have it for HD/PD, but I am getting a little concerned.

Should it just be run in more? Or should I think of calling S&W?

I may be flamed for blasphemy but I personally feel that WWB is junk. I had a box or two of it that had some sort of sticky glue-like stuff over the bullet and it wouldn't feed properly. It would get hung up on the feed ramp and it was the dirtiest stuff I'd shot. I do reload now so I make my own and have zero problems with mine. Can you tell where it may be binding up? On my M&P45 I had a very sharp bur on the underside of the extractor and it was enough to bite into the brass and prevent the case rim from completely sliding under the extractor and it actually bound the gun up. If that is the type of FTF you had you may want to check there. I would personally run some more rounds through it to see and if it still persists, contact Smith and they will send you a label and pay for shipping both ways to check it out.

I agree about WWB, it was what I could get cheap locally and it was brass.

I have a M&P 9 FS with about 600 rounds of factory ammo through it(mostly speer lawman) and I am loving that pistol, no malfunctions ever. The trigger is really smoothing out on it too.

I want to like my .45 as much.

I love WWB brass but that is about it! LOL

If you didn't have any feed issues through the Remington stuff it may just have been the WWB. I found the worst stuff was in the 100 round value pack but have seen dirty 9mm and .380 too. My M&P45 loves my 200 grain jacket rounds I load and with the exception of my self-defense stuff I've bought, my M&P45 hasn't seen a factory round ever (don't read that S&W warranty people LOL) I would maybe try some Federal ammo and see if you still have an issue. I don't want to bore anyone with the story but I thought I had messed up when I traded my G17 for my M&P45 because of the issues I had. Initially it wouldn't feed a magazine without jamming on 8 of the 10 rounds. I about puked because I thought I got a lemon...but after a few moments of massaging the extractor with some 400 grit paper, she is now 100% all the time. She has actually replaced my beloved Glock 21 as my favorite and most used and trusted piece; give it some time and run a few more rounds and see what happens. Is the gun new or used? Just remember to keep the striker channel clean, don't use any lubricants anywhere near it or it could gum up and cause a few problems. That might be the first place to look; do a strip of the slide itself, removing the back plate and striker and running some q-tips in there to clean it out if you have any further problems. Stick with that puppy, you'll love it as much as that 9 once you trust it.

Brand new, dark earth with full trijicon factory night sights. I love the look and it feels great in my hand.

I do recall burrs on the rim of some of the ejected brass, maybe I can get someone that knows something to take a look at it.

I confess to knowing how to strip the gun and brush it out and put a couple dots of rem oil on the contact points shown in the manual, not much beyond that as far as the inner workings of the pistol.

I had a failure to fire today, the round was in battery, but the striker no clicky, no nothing.

I found while dry firing that I could induce this type of failure with the right pressure on the slide. After much thought and study I found that the sear engagement surface and the striker safety release surface on the trigger bar were too close together and the plunger was causing the trigger bar to disengage from the sear as the rigger was being pulled. I took a small screw driver and bent the two pieces ever so slightly apart, I'm talking a half millimeter fixed the issue.

Beautiful gun, one of the ones I want to add to my collection. Mine is an older model, black with the thumb safety and while I wasn't too sure I liked the idea of the safety now I actually love it. It is more of a thumb rest than anything but I like having it there. I can't do a complete strip from memory on the slide; when I first encountered my problems I completely stripped the slide but haven't done it since. You Tube had a video that helped when I decided to do it.

Update:
I have went through another 150 rounds of the Rem umc target and 100 rounds of Aguila(noticeably hotter stuff) with no issues. I am feeling better about it, I will feel much better after a couple more sessions with no FTFs.

 

[DustyDawg48]

Excellent! Glad to hear it. I have heard some people saying their M&Ps did need a few rounds through them to smooth them out. Probably the exception more than the rule. Keep running that puppy! Mine was used when I got it and I've put getting on close to 500-600 since late last year...maybe August or September through it and it's now my favorite gun...so much so that I am looking at picking up another.

Wow, too many shield posts.

After a couple hundred more rounds with a couple more failures I am calling S&W today to get a postage return slip.

I can't trust the pistol to shoot round nose 230 grn factory ammo(WWB, Rem umc target, and aguila have all had ftf) and I'm sure not going to stake my life on it with HP ammo, and that is the idea, afterall.

I had a similar problem this weekend. My wife bought me the M&P 357 for our anniversary. I put two boxes of the WWB 357 sig ammo through it. The first box had one round not fire, the second had two rounds not chamber. I was really disappointed. We have a 40 and a 9, put probably 600 rounds through both with the WWB, and never had a problem. I hope its the ammo and not the gun...

I absolutely hate to hear that, but contact Smith and let them know and then keep us posted. I just managed to pick up a full-size M&P45 in FDE to complement my black 45. No chance to run it at the range just yet though.

Good luck and let us know how everything progresses!

I got the return slip today and will be packing it up.

I really don't know what is up, I am close to a thousand rounds of factory 230gn ball ammo through it, with about 10 failures to feed, that is way too many.
The feed ramp is mirror smooth and shiny after that many rounds have slid up it, spring feels strong. It should run like a clock by now.

My 9mm M&P FS has none, no failures, in 1000 rounds.

After a friend saw how good my M&P 45 shot, and a couple of sample M&Ps, he ordered one. The first time out shooting it wouldn't feed more than 50%. We checked it out and found the extractor hook had a very sharp burr edge. It was gouging the case rims in the same way on each round. This kept a lot of the rounds from going into battery. S&W took it back and it was returned to him, working 100%. Now it's his favorite duty pistol. They should do the same for you.

That is exactly the same thing that was wrong with my M&P45...and the reason the guy I got it from was in such a hurry to trade it. It was obviously not feeding for him and so he put it up hoping to be rid of it...but with a bit of luck and through the process of elimination we found the same problem with the burr...and some 400 grit sandpaper and about 5 minutes and she runs smooth as silk.
