Well...I hate this. I've sung a lot of praise for these pistols and I've defended them in a few threads for those nay sayers, but damn it if I'm not going to have to send the .40 back for repair. I put 250 rounds through it today, with the first 200 flawless. VERY nice shooter by the way, with pretty soft recoil. Accuracy was good, but still not up to my HK P2000 or SIG P229 standards. I'm pretty sure it's the trigger adjustment, cause when I beared down I was doing 1" groups at 10 yards. I was just getting ready to shut it down when right after the 11th round the magazine popped out after failing to feed the 12th round. I thought I had hit the mag release button. I reloaded the mag, took care to stay away from the mag release button, and it happened again. I shoot shoot thumbs forward and high, so it's not likely this would be the case anyway, but I sure would have liked this to have been the issue. In the SIG world many believe their pistols are malfunctioning when the slide locks back prematurely, it's due to riding the thumb on the slide catch however.

Anyway...Let's say I still love these pistols, and the shooting experience with it was excellent, but obviously I have a defect. The sad part is that after 30 or so handguns or all makes and models this is only the 2nd time I've ever had to send a pistol back for warranty work
It is a Rev N model for whatever that's worth, so it was supposed to be the updated frame.

Guess I'll see now what the Smith and Wesson customer service experience is like.

It's been pretty solid for most people.



Out of curiosity, you peek down the magwell form the top fo the frme and note the condition of the mag catch and "spring"?

The mag release is easy to remove. I would try that before sending it back. You could try reinstalling it so the button is on the opposite side of the frame.

Make sure it's clean, not binding on anything, etc. Could be something simple causing the failure. Any doubts, send it back.

My last 2-3 trips to the range the same thing was happening to me. I switched the mag release to the right side but it still happened. Even had someone esle shoot it and the same thing.

Well last night I cleaned everything up & used degreaser on the mag catch & all the mags ..... problem solved.

My guess is when I was cleaning my mags I was leaving enough oil on them to allow them to slip out while shooting. I went 200 rounds today with not one drop out after using the degreaser on them.

Zippy...where exactly did you apply the degreaser to the mag catch? What about the mags? What degreaser did you use?

I'm glad it worked for you, but it just seems unlikely that is the long term fix, although I will say everything involving the magazine catch mechanisim seems solid and working other than he magazine popping out. I also noted that this problem is on the "mechanical problems" section of the forum.

Oddly enough, my MP40 did this exact same thing. The really really odd thing is that it also did it right after the 200 round mark. I had to send it back and S&W gave me a whole new frame. Where it gets even weirder is that now the serial number on my frame does not match the serial number on the box. :?

That would make it a bit tough if you were to sell it. Has it worked ok since you got it back?

Well I hope it's a long term fix .... at least till I get my .22 so I still have somethin to shoot. But we'll see i guess, my M&P is only 1 month old so if it still acts up I can just send it to get fixed.



I used Tetra Gun Action Blaster,



http://www.tetraproducts.com/product_view.asp?ID=5



It's about $6 a can. I took out the entire mag catch/release button, cleaned it with a soft brush and then sprayed the entire thing with above. I took the mags apart and sprayed the metal casings all over, paying close attention to the cag catch notch. Used a rag to wipe them down.



Like I said, it seemed to work as I went thru 200 rounds today without one drop. Yesterday was tap & rack hell, After just about every shot (or at least every other) the mag would drop so today was a 100% improvement.

OK, so the M&P has a lifetime warranty and they pay shipping. Is that right? What is the usual turn around time?

Mostly, except for one bizarre looking failure to feed a single round of Winchester Ranger right after I got it back.



Turn around time for mine was less than 2 weeks I think. I was not lucky enough to be awarded an extra magazine with my return, though, like some on here have got.



If you contact S&W by email, they will respond with an email containing a Return Number and instructions on how to fill out a FedEx label (you mark the box that says the recipient will pay for the shipping). So yes, they cover shipping both ways.

Be nice if they furnished a magazine tool to help load. My fingers are sore, because I like to fill'em up. The lack of one makes me want to shoot my XD's more.

I use the HKS model 940 magazine loader for my MP 40, Mp 9mm compact and my SW9VE. Works fine, goodbye sore fingers. :wink:

A magazine loader did come with my MP .40


Yeah and my house came with a lawn man. He's called The Old TxPhantom!

Jagman may have his M&P confused with his XD (if he has one). They came with a loader.


Nope don't have one XD that is. My .40 MP came with a loader, but frankly wouldn't have mattered to me one way or the other.
