Late '50s era K22 Combat Masterpiece.
Same gun with the grips it was wearing when I got it. They are mismatched which is why I put some Culinas on the K22 CM.
18-3
The 18-3 has tight charge holes and they need to be cleaned out every 8 to 10 cylinders. The K22 CM is a sweet package, shoots tight groups with pretty much everything and the charge holes do not clog. Been contemplating selling the 18-3, but you know how that normally goes.
