I have been reading some things on the interwebs recently regarding some new production M&P (9's mainly) which are having serious issues with the barrels. Specifically, there is an issue with the barrel crowns. I saw this recent post by Chris Costa on his facebook, which was very cryptic regarding the issues with the gun. The post shows two targets with a splatter of what appears to me to be keyholed bullets or fragment holes throughout the target. Costa indicated that these were from the barrels in the new M&P 9's "shotgunning" the target. There was little information as to the nature of the damage to the guns and there were no photos of the guns themselves. From Costa's post, he makes it sound like this is a recurring issue with recently produced M&P's. See his post here: https://www.facebook.com/Official.Ch...79194195445820
I also chatted with a gentleman online (also on facebook) who said that his fairly large police agency had attempted to transition to the M&P series a couple of years back and he personally had an M&P with serious issues with the barrel. He said that the barrel broke near the muzzle, but would still fire. I was unable to obtain any photos of the damage. Sounds similar to the issue Costa was addressing in his spacebook post.
My question is, are these guns experiencing some serious QC issues that we should be aware of? Does anyone have any more information about these incidents to include photos of the damage? I couldn't find anything else online other than these couple of instances.
I wasn't sure if this belonged in Autoloaders or Armorers, so feel free to yell if I posted this in the wrong forum.
