I have the Lone Wolf .357 conversion barrel for my G23.
Have noticed that when aiming at center of 6 inch target circle,the .357 rounds will impact to the extreme upper right of target. The S&W 40 rounds will be on center.
Doesn't seem to matter which brand .357 ammo is used.
Was shooting American Eagle FMJ and Underwood JHP.
Could the different style barrel rifling between the OEM Glock
barrel and LW barrel be the cause,or the sights on the G23 just tuned for .40 and not like a Glock 32 would be?

Sight related POI would be affected vertically, not horizontally.

Have somone else shot with the LWD barrel and if it is the same, I would contact Lone Wolf and ask for a replacement barrel.

I've read that the sights on the G-23 and G-32 are different heights.
