That's a nice pistol. Stingers or Velocitors are what you should have in it if you're carrying. I've been considering carrying my M&P .22 Compact. That thing's a machine -- I've run thousands of rounds through it, only Mini-Mags and Stingers, and it's never had a malfunction of any kind. Not once.
You just can’t beat CCI. I used to run their maxi mags in my Keltec PS 90 .22 mag. I also like Hornady.
