By far, my hands down favorite is my Colt Woodsman, built in 1937 as far as I can find out. It's extremely accurate, and probably the smoothest action I've ever shot with.
It's a toss-up between my LCR 22 and my SR 22. Both area a blast to shoot. The SR22 is more accurate...due to the adjustable sights. Both have lasers for close-up fun.
Though I've already posted, it just came to me that besides the Ruger Standard, I had a nice Ruger Target in SS that was a bell ring. I also have had a early, 1933 Colt Woodsman "Sport" that was very nice, and S&W mod 18 that was awesome. TJ
It is a Weaver #306S top mount for a Ruger 22 Automatic. It is a weaver rail mount for pistols that don't have scope holes drilled in them. I had some customers ask about them when they first came out so I thought I'd test one and see how durable it was with this style of mounting. You leave the rear sight base on but remove the adjustable portion of the sight by popping the sight crosspin. It mounts via a screw down into the base using the elevation screw hole. As long as your rear sight base is secure the mount is very stable. It works surprisingly well. I was a skeptic at first but the mount has proven itself over the years.
