Hello all. I'm wondering if you can offer your expertise and help me out with a concern I have. I recently purchased a FS M&P 9 and the factory barrel that came with it looked completely trashed inside the bore(and it doesn't shoot much better). So I called S&W and they wanted me to send the whole gun in just to get a new barrel. I decided I'd rather not wait and ordered a factory 9mm barrel from MidwayUSA. Now, the funny thing is, is that the barrel I got from Midway lacks any sort of crowning and the rifling goes all the way to the end of the muzzle.
Seen here-
The barrel that actually came with the gun was properly crowned, but the machining inside the bore seems to have been lower quality and the gun doesn't seem to shoot as accurately with it.
Here's the one that came with it-
Hopefully the pictures depict well enough what I've tried to illustrate.
My question is, the gun seems to shoot better with the barrel that I got from Midway, but could the lack of proper crowning affect accuracy? And should I just send the gun back to S&W to get a properly crowned barrel that is better quality than the one that came with the gun?
Thanks for your input.
