Too bad that great little piece is only a six-shooter and not an 8, or 9, or ten-shooter! Fine little pistol.
So you shoot Stingers?
You might try shelving them in favor of CCI's Quik Shok's (basically the same as a Stinger - same velocity and bullet weight), but the Quik Shok's bullet is prefragmented into four peices when it impacts. Also, the Velocitor is another CCI wonder-round with a GoldDot -type 40 grain HP bullet, the fastest in it's class as well.
I've shot both rounds in a 4 5/8" Ruger Std MkI, and noticed quite a significant increase in power and report over usual rounds. The CCI Stinger would be my third choice to the other two CCI rounds if I ran out of them.
Too bad the M63 Kitgun is now a rare commodity.
