I have a "perceived large difference" in muzzle rise, in three 1911 .45 ACPs Commander Models, from 2 different mfgs, using the same ammo in each. The 1911s weight are nearly identical with all steel frames. Less than 600 rounds have gone through each. Two are from Nighthawk. (Talon II and T-3) a.) The larger perceived muzzle flip. One is from Wilson. (Professional) a.) The least perceived muzzle flip. I was wondering if anyone else has experienced this and what could cause such a noticeable difference. Integritas AuP PS This is not one mfg is better than the other (since I own both) but as to what would be the cause of this? Shooting them side by side... Everything else being equal... It is very noticable Wanna kill these ads? We can help!
