If you were lucky enough to find a never-used GI model, it would be oh-so-valuable. I wouldn't shoot it for that reason, but if you did, you would find it sadly lacking in accuracy. They were what they were intended to be: a close up weapon to use in the trenches in World War I, and a last resort weapon in World War II. You can shake them and see and feel the rattle. None of them were tight fitting unless worked on by the armorer for target use. The sloppy fit made them reliable. I remember in the 70's when the gun shops were full of them, selling for under $100. Who knew they would have become such sought after collectible pieces.
