These are my .22LR handguns ranked in order of preference:
1. Model 17-3
2. Colt Trooper MkIII
3. Browning 1911-22
4. Model 617-6
5. Ruger SP-101 (1st gen.)

I also have a .22LR kit for my CZ SP-01 that is amazingly good.

I am getting ready to buy a Model 41 to round out my collection. I'd love to try the Buckmark, but I hate plastic parts of any kind on guns. (The 1911-22 has a plastic front sight that I have to super glue on, but it is super fun to shoot.) The Ruger is getting a trigger job & new springs, and the 617 will get one too.
