I own both a Glock 23 and a Glock 35. I have Dawson Precision Sites on both of them. On the Glock 35 I can consistently get a 2" group at 25 yards but with the Glock 23 I seem to not be able to manage any better than a 4" group and that is shooting using a bench rest. I am using Federal Hydra Shocks 165gr or Federal American Eagle 165gr. I know the G35 is going to always be more accurate than the G23 but it just seems I should be able to manage better group at 25 yards with the G23. At 15 yards I can manager a 2" group with the G23. Anyone have any thoughts, could it be the ammo I am using? Please see attached photo of my 10 shot grouping with the G23 at 25 yards. Note that each square on the target is 1" x 1"
