Well, I like all of the .22 handguns that I currently own. I no longer own a single six. They are great guns and built like a tank, but too slow to reload to suit me. If I am going to poke empty cases out, I like bigger holes. I no longer own the Sigs or Buckmarks. My autos are Ruger and M41. The SP101 .22 is another built like a tank handgun. A bit heavy, but hard to find and you are lucky to own one. I have only seen one for sale and bought it on the spot - NIB. I don't shoot it quite as well as the Smiths. All others are Smiths - M17's, M18's, M63, M317, M617's.
Yesterday we burned up quite a lot of ammo in the 617's and M41 and it sure was fun. Also worked out with the 9's, 40's and .45.
