Yup, thought it was the shooter, but, another buddy had the same results.
It is a police trade-in and came with GNS, and the rear was adjusted way to the right.
(it shoots to the left, otherwise)
It groups well enough. Fair amount of slop in the Gen2 barrels, but, nothing that would impact its effectiveness for defensive purposes.
Nothing is obviously wrong either with the slide. Barrel port looks the same either way.
Maybe the locking lug on the barrel is either slightly "off" or the locking block is the issue.
Hard to tell.
Thinking I might try a new locking block first, but, wanted to get opinions first from other shooters before I start spending money.
