At least 12 over 100. All have been shot at least once, most a couple of times.
A couple of early Colt autos - M1911, 1903 Hammerlesses and a 1903 Pocket Hammer.
A couple of Colt revelovers - New Service, Police Positive, Officers model.
A handful of S&W 38 & 32 double actions.
A Luger and an early Springfield M1903
One of the 38 Double Actions is pushing 140 and I've brought it to the range a number of times. The Colt Police Positive in is surprisingly accurate with a 148 grain hollowbase wadcutter. The old Officer's Model has sights like a rifle - tiny post up front and small opening of the rear. It works pretty well for shooting a gong at 100 yards. The Colt M1911 has a replaced Remington Rand slide that was accurized at some point, had target sights added is very accurate. I've probably put close to 2,000 rounds down range with it.
