Here’s a picture of my new Mark IV 22/45 tactical and a pic of my bicentennial Standard I purchased NIB in 1976. I’m new to this forum but I’ve been a Ruger fan for quite some time. I just picked my Mark IV up 2 weeks ago and waiting for the weather to break to get it to the range. I had a Kidd compensator sitting around looking lonely so I added it until I get a can for it. I purchased the Standard new in 1976 to run my trap lines.
