Disappointed
This conversion barrel looked like a great option for my M&P Shield 40 caliber. I’m not sure what the issues are, but you it shoots off target. With my original 40 caliber barrel it hits where I aim it. With the conversion barrel I can’t use the same sight picture I use with my 40 caliber barrel because it shoots low. I mounted the pistol on a stand and shot it with each barrel and the conversion barrel shoots low. It also fails to eject the spent casing at least once per magazine (and yes, I bought 9mm mags too) but that could be the ammo.
