Hi - This is a friend's gun and her family had it in a drawer for decades. Want her to at least have it at her disposal for HD so trying to figure it out. I know about as much about revolvers as quantum mechanics. When the cylinder is out/off to the side, you can pull the trigger and the hammer pulls back and drops. With the cylinder in place, the trigger can only be pulled back about 3/8ths of an inch (same with hammer coming slightly back). Otherwise, , it looks great. A little wear on the trigger guard left side and slight wear at barrel end, so it isn't like it has been abused. More like a revolver that has been carried but rarely fired. A piece of paper barely fits between the cylinder and the barrel. Also, trying to figure out what ammo this thing takes. Was told Corto SW 38, but no go, the shells fit way tight in there LOL (no need for the Kevlar gloves, goggles and Dragon skin test!). 38 Long Colt seems to fit in there though. From the name, I would have said '38 special' but several people have said no, that the revolver is too old for that ammo. Does anyone know definitely what ammo this takes? Low power, low recoil - shooter is small. I could also take a video and post if that helps. Thanks.
