Pretty much anything that goes "boom." I have a repro blunderbuss, a couple of repro sea service pistols, a replica Kentucky Rifle in flint and percussion, as well as a repro LaPage flintlock dueling pistol...I have SAA repros from Uberti, and lever action rifles as well as SxS hammered and non-hammered shotguns. Fast forward to my Glocks, Beretta, and 1911s, CA revolvers, Ruger Chargers, a couple of GSG fun guns, Winchester 1300, and my M1A...My next acquisition will probably be a Saiga 12 semi-auto.
