Ok - so I picked up a 90% S&W yesterday. It's around 90% condition, so it'll make a great carry rig out in the woods. It's stamped 25-2 and has a s/n that starts with three letters. The barrel is 4" and marked 45 Colt Ctg. My understanding, and hopefully still is, is that it's a .45 long colt gun. Looking around online, I've seen conflicting info that 25-2's are .45acp and 25-5's are .45lc....... Anyone have one of these? info on it?
