Hello Adam;
I have a Ruger Mk II that I've 'modified' slightly....I put a set of Millet adjustable target sights on it, and I've added a pair of aftermarket wood grips (I can't stand the sight of plastic on a good firearm!

). I've used the gun small game hunting, as well as a back up while bird hunting (for coons, skunks, porkies, and other critters that will give the dog fits).
Much to my dismay, the Ruger is the
only rimfire handgun I own.......

Guess other priorities, like food & tuition, got in the way!

I always liked the looks of the Ruger single six, and the S&W 617. I also liked the looks of the Colt Woodsman, but the price of those pieces have gone into orbit!
I don't know too much about the newer .22 rimfire side arms on the market; I thought about getting a CZ Cadet, as it looked like a good training gun to compliment my CZ75B, but I am still a single rimfire handgun owner.....
