I have been a S&W fan since my teen years (45+ years). I now am 61 and I bought my son his first (NEW) pistol for his birthday (M&P 2.0 9mm). I also bought 4 different types of ammo. Federal, American Eagle, Remington and Blazer Brass. expecting one would fire better than others. As excited as he was to get to the range, he was quickly disappointed. Every single brand of ammo jammed. It was rare to get 2 rounds in a row without either having to remove the spent casing manuallyor a dry fire from the next round not loading.
I tried 2 seperate magazines. I tried all 4 manufacturer ammo. I tried full magazines and I tried only loading 3 or four at a time. Nothing worked.
Has S&W gone down hill tramendously? Did I just get a lemon? Is there anything else I can try. My son is very discouraged and wants me to get a glock as a replacement. Im not a big fan and would really like him to be hooked on S&W as I was. Some day my boys will split my collection which are mostly S&W, but revolvers.
I could really use some advice on what the problem could be. Has anyone had this problem and how did they fix it?

My M&P 9mm Compact 2.0 has always worked great

I'm very sorry to hear of your troubles, especially when you bought it new and for your son!

Mine is the 9mm M&P 2.0 Compact and always worked great right out of the box. I use mostly Blazer Brass and Winchester White Box whichever is cheaper at the range.

Mags all work fine, even with the 2 round extender sleeves in place on the mags.

My M&P does have a somewhat "wonky" trigger that sometimes feels like it is "staging" but it really isn't and the Manual even cautions about staging, or attempting to stage (some call it stacking), but if you are sure you or your son did not try to lightly squeeze (like we were all trained to do since boyhood) and still have those problems I would do the following in this order:

1. Return to the selling dealer. YOU are their customer and they can return it to Smith & Wesson a lot easier than you can as well as keeping you a satisfied customer.

2. If the selling dealer refuses you can at least call S&W customer service and hopefully talk to someone about the problem, especially with a bunch of different brand factory ammo. The gun (at least mine is NOT rated for +P+, but regular 9mm and 9mm +P is shown in the Manual as ok.

Since the gun is brand new, and you probably have your receipt and all it SHOULD be covered under warranty and it doesn't sound like a problem you or your son created first time out.

By the Way.........Welcome to the Forum from Virginia. Please come back and let us know how you make out with this issue. Have not really heard any bad things about the M&P line, but I'm not an expert and I'm sure some others will be along who probably know a lot more than I do about the M&P line of semi's

Sorry youre having these issues. While Not an expert on the M&P 2.0 9mm, I do own one and have had "0" problems. Maybe 4 to 5 hundred rounds down range. All factory ammo, mostly Blazer Brass and Norma 124, 9mm.
Many possibilities as to your issues. Did you give it a good cleaning and lubricant to factory specs? Maybe polish the ramp?
Mine is a great gun, and shoots great if I do my job.
 
That's not right. These are normally very reliable. My two have been 100% since new. I second the advice to call first your dealer to see if they will help you. If that doesn't work out call Smith and Wesson customer service. They'll email you a shipping label so you can send it in to be repaired. Will take at least a couple of weeks to get it back, but they are really good at making things right.
 
Has anyone else besides your son tried shooting the pistol? This number of malfunctions is just so far out of the norm for this series of pistols. I have no idea how much experience your son has with shooting semi-automatic pistols but it kind of sounds like limp wristing or failure to get a firm locked wrist grip on the pistol.
 
I would break it down and clean/lube really well. Check all the parts closely like extractor, feed ramp and chamber looking for burrs, cracks, etc. also make sure that the recoil spring is in correctly. After that I’d try again. And have someone else attempt to shoot it also.
If that fails, then I’d get with customer service and request a prepaid shipping label. You can legally do this, no dealer required. In fact, many dealers wash their hands of a problem once it leaves their store. S&W should make it right and normally do.
I own several M&Ps and can only recall one going back twice for slide rusting. The replaced it the 2nd time back, but this was like 12-15 years ago.
 
What you describe sounds like either there is some major limp wristing going on, or something is stopping the slide from moving freely. A field strip, clean and lube seem like the first step in that diagnosis. After that it's time to examine the shooter's grip, either for limp wristing or riding the slide with a thumb.

My M&Ps are generation 1 guns and have never done what you describe when fired by my wife or myself. The only time an M&P has given me issues was when a very early production range rental kept popping out the mag for no good reason.
 
Welcome to the S&W Forum! First, I presume the pistol was properly cleaned and lubricated before its first use. How experienced is your son with semi-auto pistols? If he has little to no experience, I would suggest that you or someone with significant experience test fire the pistol. If it still malfunctions, then the dealer may offer a swap or contact S&W for warranty service.

Yes, I've had this EXACT problem...

Take out the mags and load them full. Then unload them by flicking with your thumb. Do they all feed out of the mag or get hung up? I sent two mags back for that problem and they sent me two new mags with exactly the same problem. I found that the the mouth of the case is getting hung on the front of the mag.

I sanded down the front of the mags and took them out for a range test yesterday. Not a single problem.

I have written about this with pictures in the M&P auto pistols forum. It shows how much I had to sand down the fronts.

After I got this fixed it's a dang nice gun. It's an EZ and my wife is able to handle it well.

Could you leave the link to where you fixed this?

Got the gun, it did not cycle any ammunition out of the box.

After a talk to my (very experienced) range officer I took his advice to use high powered hollow points.

I did that, first Hornady extreme worked flawless, then I ordered Sellier & Bellot SB9A (115gr, 418 ft/lbs) and fired 300 rounds without any problem also 100rds AAC (124gr / 364 ft/lbs)

My usual PMC 9A(115gr) 9G (124gr) ammo, lots of reman and almost any ammo (including Federal) below 350 ft/lbs is NOT working.

I wonder if this is a bug or a feature. Maybe the recoil spring is too stiff.
 
From complaints I see on this forum and others, it strikes me that much of the 9mm weak-sauce plinking ammo has become even more neutered lately. I don't even try to use 115gr ammo these days unless it is self defense stuff or S&B. Forget Federal or Winchester White Box except for their NATO load. I set the bar at 124gr @ 1150 ft/s for reliable operation, and I prefer more. I generally won't touch 115gr that isn't rated 1200 fps or more.

Trouble is I have seen others around the Web suggest that 1150 for 115gr is "the standard" for 9mm. I find this laughable. It is a military cartridge specced for a whole lot more, and many (most?) new guns are sprung accordingly. There's even a member here who sold a collectible military pistol, a Steyr GB, because it was not reliable with weak sauce plinking ammo. I own a GB, and ejection is lazy with 124gr Blazer brass and only really gets going with 124gr self defense ammo or stuff marked +P. But, as this is a military gun, I'm hardly surprised.

Given these pistols are aimed at the self-defense/LEO markets, S&W may be using a recoil spring more appropriate for NATO, +P, and perhaps even the U.S. Army's new 9x19 which runs at the top of +P pressure specs. I remember when I bought my Tanfoglio TZ-75 Series 88 and it would stove pipe most white box 115 and 124 grain FMJ ammo. It ran perfect with European made ammo and U.S. made +P ammo. Replaced the recoil spring with one that was 2 pounds lighter and it ran reliably with the cheap U.S. ammo.
 
I tried a wide variety....

I tried at least 4 loads. Two of them were range ammo and two were 'defensive' ammo with plenty of punch. (Common brands though) They all failed as did any extra ammunition of various types I had leftover.

I don't think the OP's gun is an EZ, just a regular M&P.
