Defective M&P 9 Barrel

I'm going to guess its from chambering the barrel, if they do it from the muzzle. Must have fallen asleep on the reamer!

nope, from the breech. My bet would be that the mandrel chattered as it exited the barrel. I probably shoots just fine, but looks like crap. I'd not want it on a new gun, but if i purchased a used one that looked like that i'd just shrug as long as it shot. and it was cheap ;)
 
EDIT: S&W replaced the handgun, facilitated by the LGS. They told me to choose carefully, since they won't do another replacement. The replacement had a worse trigger than the one I originally bought. When I brought it up, they told me to get a Glock...
I don't particularly like Glock but this is actually good advice. To say that S&W's quality control is hit or miss would be an understatement. I don't understand how they manage to stay in business.
 
Given that I own and shoot both, and have more Glocks than M&P's, to say the average Glock has a better trigger than the average M&P is a bit.....odd. Different, yes - better?

PS - what did the upsell to the Glock cost you?

I don't think that a different handgun was ever an option. It was just a straight swap for another M&P 9, with the crappier trigger.
 
You should listen to enefgee, he knows what he's talking about.

I don't know which LGS you're talking about, but if I got that kind of attitude from a store that wanted my business, I think
I'd tell them to take a long walk on a short pier...
 
Looks like your gun had a stuck bullet which was struck by a second bullet and ringed the barrel.

I'm not sure what your seeing in the pic, but it doesn't look like a ringed barrel at all. No bulge, to tell tale shadow or fouling in the "ring". It looks like tool chatter bit off the last bit of his lands.

Your LGS doesn't deserve any more of your business if they treat you as you say.

And Glock is perfect or better? I have seen some #### come out of Glock's American plant to. No firearm manufacturer is perfect. S&W is far from perfect. But they are better then a lot of them out there. Well at least they are better then newer stuff from Remington, Chiappa or Marlin anyways. :)
 
Remove metal slowly -- when doing M&P triggers removing material is easy -- putting back on is, well pretty much not going to happen.


I carry an M&P and have a few others too -- a striker fired gun is never going to have the trigger pull of a good hammer gun. You need to accept it for what it is -- shoot it a lot and get used to it, or go back to hammer guns.

The barrel never should have left QA - but it happens and it will be fixed, the LGS is not replacing the gun, S&W is - unless your LGS is running a scam and planning on re-selling that one to the next guy who walks in.

That's one weird looking ringed barrel..

The groves are perfectly fine and only 3 of the lands are "dented"
Looks like it got pulled from the rifling machine while it was still running.

That wouldn't surprise me. USA is the new China as far as shoddy workmanship and poor quality control is concerned. That's why I try to avoid buying recent productions "Made in USA" firearms whenever I can.
