I don't know the first thing about these guns, but I bet I can learn here! From what the dealer told me, they are real nice for the price! This one must be a arsenal refurbish, it looks brand new! Stamped on the right side OP 97, that must be when, also stamped X 54, that must be the year. Got a holster, spare factory mag, cleaning rod, and 6 packs (96 rounds) of surplus ammo for $225 OTD.
