Make sure it is a Super Single Six. They have a factory hammer block installed. If you get an older one you can get one installed in case you drop the hammer unexpectedly. I very seldom use the 22 cylinder. The magnums are 6.99 a box of 50 here. I have a 6 1/2" barrel and can drop cans at 100 yds with it. Although my prefered distance in 25 yrds. Loading isn't a problem once you get used to it. I think a single action is as much fun as my kimber 1911. Here's something I made on a Hot day, out of boredom. It's not particularly good. But it will give you an idea of what I mean by fun.
