Glock Samson finally got some mag baseplate grip extenders AND a 9mm mag for the forthcoming .40 s&w to 9mm conversion barrel (looking forward to saving $0.10-0.20 a round for sure)
So I’m cross eye dominant, and as a result pulling down left. Will post here as I get more muscle memory reps in to reset quickly even if my grouping is a mile wide. Next round will experiment with a slight head turn to take my right eye ever so slightly out of the equation.
