So I finally have these guns in my hands. The one my step father is getting is ser#10002**... Less that 300 model 12's after the one millionth!!! Pretty cool if you ask me. That one is 1943, the other two are 1950 and 1957. The 43 and 50 are solid rib, the 57 is smooth. The 43 and 50 both have "full" stamped on the barrel, the 57 has "cyl"and a much shorter l.o.p... I'm assuming these compensators were all installed by a gunsmith. The 50 and 57 look brand new! The 43 not so much... Best part is, I'm only $170 bucks into the two of them!!! I really want to give one to Jordan, the kid I got into wild bunch, but I really want to keep them both, they are so pretty!!! Decisions, decisions...
