Have to share this...
In my misspent youth, I shot with the Marine Corps Reserve in Oregon. The pistol team Captain was a Major (then) who will remain nameless to protect the guilty.
He had an accurized Government Model for target shooting. He used two main springs, one for wadcutters and one for hardball. With the hardball spring and ball ammo, it worked pretty normally. With the wadcutter spring and light loads, the empties reliably hit him in the face. He wore safety glasses and ignored it.
He had offers from all sorts of armorers to "fix it", but it shot too well and he was afraid any modification would screw it up.
However.... in slow fire, the two poor souls to his right and left could never shoot a decent string. They'd be watching that brass bouncing off his shooting glasses.
He also had a High Standard .22 match gun. The empties went 90 degrees from the line of fire and just barely slower than the bullets went down range. At least it looked like it.
