Today went to the range with a few buddies, I brought along my S&W m&p40c. I just recently had a trigger job done by BEC(thanks Lou)and wanted to shoot it. First things first, it shoot great(when it wasnt acting up), and was very accurate(ounce I figured out where to hold). But nonetheless it had problems. I had 7 failure to feed. Seven........seven FTF. Wtf!!! My firearms are well lubed, so I know thats not the problem. I bought it brand new and am the original owner. I have 3 mags, all 3 new, and all 3 hang up. Have two question for m&pc owners. One, I kept shooting low, even before the trigger job, so I tried holding the front higher than the rear sight( top of the rear sight met half way of the white dot of the front sight) and shot dead on. It's this normal? And second, the recoil spring. When shooting, it felt weird, instead of solid feel, it felt like a "lazy" slide, a "ka-chunk" if u will. I noticed when I first bought the pistol, the recoil spring doesn't fully push on the barrel. It's loose, it slightly has pressure on the slide and barrel. I called S&W about this, and they said its normal for the compacts, theyre loose fit. Honestly I think that's whats causing the FTF because of the "weak" recoil spring. I put 600 rds prior to the trigger job , and every great while, the gun would not a feed a new round. The slide would stay open, not locked back, halfway stripping a round, then go into battery by it self after like 2 seconds. Anyone has this experienced this with their compacts? Am definitely calling S&W again about this!!

I've got an M&P 40c as well and I also feel the "lazy slide" as you call it. The spring in the compact models is definitely a different feel from the full sizes or other gun companies. However I've never had an issue with it.

It sounds like this is a new problem, since you put 600 rnds through it without issue. I'd re-clean it and try again. (make sure you dont use much oil, I see that you said its well lubed, but be careful, with these guns too much lube is bad, I've noticed the gun actually likes less lube than more)
 
What cleaners and lubricants are you using?

I personally use BreakFree CLP. I lay the parts out on a sheet of tin foil spray BreakFree on all necessary parts & let it sit over night. BreakFree is not fast acting... It works amazing if you let it soak into powder, lead & copper fowlings. Break free has Teflon in it & I find on most guns I don't really need to lubricate afterwards (unless a very tight match gun)

I like to sit back with a cold one (beer)... and take my time cleaning my guns slowly & meticulously. (NO AMMO, EVEN IN THE ROOM WHEN CLEANING)
 
I had experienced FTFs in my M&P 9 full when I first bought it. The issue was with one magazine's (MA cripple magazine) follower catching on the cutaway from the magazine catch. It would fire four rounds then fail. Being a lefty, I switched the magazine release back to righty and the problem disappeared. I took the follower out, gave it a haircut and 1000 rounds later, not one FTF with the magazine release back in the lefty position, where it belongs.

It's funny to me that despite all the BS I have had to do to my M&P's, I love them way more than my 19 year old Glock (which has never caused me grief).

So it is normal for this to happen, it's crazy to me. I owned/have various Glocks, owned two Sigs, and had a sigma, and I never had any problems with them, or felt the way the M&p did. I don't over over lubricate my firearms, a drop on each rail, and a drop on frame rails. That's it.
 
I haven't noticed anything like what you mention with my M&P40c. It seems to cycle just the same as any other gun I own.

This I don't fully understand.
 
Do you get the same issues with other ammo, or just the Tula?

I never had a problem of any kind in my Sig P226 until I bought some Tula 115 grain 9mm. Felt underpowered compared to other 115 grain offerings from Federal or WWB, and it stovepiped my P226 a couple times in only 100 rounds. Went back to Federal and no problems since then.

Usaully, which all the guns I've owned, u need to push down on the recoil spring in order to install it, not in this case. The spring juss falls in, with hardly any contact against the barrel

Also with Speer lawman, which is a "full power" load
 
I'm babysitting an M&P .40c and I have never noticed anything like that with its spring.

It could be the Tula! My buddies 40c kept on choking on it not that long ago to see if it was gun or ammo we swapped I had wwb. It was flawless after the trade. But I would get it checked out if it feels sloppy.

so which means is not the tula ammo, plus I always use Tula ammo on my Glock's ,kahr and H&K and that never happen
 
Have an M&P 40c with trigger job from BEC. Put about 800+ rounds through it with various types of ammo. No failures of any sort. I also have a full size .40 and don't feel much of a difference as far as the recoil spring between the two. I lube it with Slide Glide light.
 
This was also happing before the trigger job, it wouldn't fully go into battery, it would close 98% of the way, resulting me to hit the back of slide to fully close it. And like I said, it would happen with diffrent types of ammo. I called S&W today, and explained my problem to them, and all the rep said," have us look at it, I'll send you a prepaid shipping label, and have our technicians work on it" but I know the end results going to be. "we've gone over the pistol, inspected it, shoot it, and everything is within spec".

so are you going to send it in to S&W?
 
I really don't want to, but it's my ccw, and it's not reliable. Again used lawman which is said to be loaded to the same spec as the gold dots, and it still happens. The weirdest part again, has to be the spring. Everyone's saids they're spring looks ok, while mines when you install it, move the slide side to side, the recoil spring moves also side to side. Every gun that I owned, you have to push down on te recoil spring to install it, usually holds pretty firm, this is not the case with the M&P.

I shoot my M&Ps pretty much bone dry and they run flawlessly.

yep, me too, couple drops where the instructions say to and shoot pretty much anything, lots of WWB, but most anything.... heck got 5 M&P's they all work flawless.... if I had one that wasn't right, I know I wouldn't hesitate to send it back ... unless I just wanted to post on BB's and whine about it.. that usually fixes it...then there's always talking about how my Glock shoots anything... that'll fix it... ya that's it!!1

Not every gun is good he mite have got a bad one,and he wanted to know if any one had the same problem and knew what was wrong with it and how to fix it,and If it's b's then don't even post go on to the next one
 
Actually, knowing that my Sig P226 MK25 Navy, and my Glock perform how they should, does makes me feel better. I merely posted to see if other M&Pc owners where having the same issues outta the box, not a smartalec that had nothing to say and posting unnecessary comments
 
I'll be honest, I've owned two separate M&P's (M&P 9c & M&P 40c) and neither had those kinds of issues. If the gun is basically brand new I think you might be better off sending it in to get looked at.
