Well Mr Smarty Pants, I will say this. After never qualifying less than expert with M1, BAR, M1919A6, M14, M60, M72-LAW, AR15C-602, M16A1, and even a 3.5RL, plus 2 years on the SBT and 1year as instructor, it wasn't my eyesight that was the problem. It was the weapon. The 1911 came out of the factory inaccurate. Poor sight picture, uneven tolerances and pitiful ammo. There was never a 1911 worth it's salt until it had been reconditioned for tolerance and used competition ammo, none of which were available when it came time to qualify. Also if you ever had to qualify with a 1911, you might remember that it always shot low at 15ft, ok at 20 and 25, and high at 30. The only folks that could consistently mark expert, were guys that could get 2 or 3 hours a week on the range, and that usually meant officers.
So if you say that you always shot expert with a 1911, I will call BS on you.
