I have a Ruger Mark in the shorter heavy barrel. What can you say about the Mark? Everyone needs at least one of these!
Also, a Dan Wesson Pistol Pack in 22 rimfire with 2.5, 4. 6 & 8" barrels and two grips. My $150.00 steal! Great for kids with the ability to change grips and barrel lengths.
The nicest shooting 22 I have is a Bernedelli Model 100. The grips fit everyone's (who has ever hefted it) hand like a glove. It just lays them in there.
I know I need another 22 but I just can't remember what it is. I hope it comes back to me when I have some money in my pocket again! ha ha!
