Shooting the Thompson

[Gil Martin]

About six years ago I bought a new semi-automatic Auto Ordnance M1 Thompson. Last Monday while working at the local gun club I got a chance to sight it in and do a function test. It was flawless with my 230 grain lead and FMJ reloads and a moderate charge of Unique. The point of impact at 50 yards was several inches low when shooting from sandbags. This model rifle has fixed sights. Fifteen minutes with a file lowered the front sight .06" and raised the point of impact to dead center on an SR-1 target. All the best...
