First build - L2D Combat Precision Match Fluted/Threaded Barrel, S&W M&P Shield 9

This is my first custom build so I'm not going to judge in depth because I don't feel I'm experienced enough yet. Here is an account of performance since the barrel swap. I've had 2 failure to feed with around 70 rounds fired. The first failure to feed was IMO due to the barrel being brand new but maybe a rough edge. It worked itself out through racking the weapon a few times. The second failure to feed I'll credit to a little too much dirt & lack of gun oil, possibly a need for +P ammo due to compensator added to my weapons. I've just purchased Shooter's Lube thoroughly cleaned everything. No racking issues feels just as smooth as the OEM barrel now. I'll be testing at least another 50 rds this week & updating my review.
