Modelled after the P226 but 10% smaller, so it's an excellent kid trainer. Very low round count, probably 300 max. I've found it to be a little picky about what ammo will cycle. Regardless of what grain bullet was used, CCI stingers, American Eagle, or other 22lr ammo that comes in boxes where the rounds hang by the rim in a tray seemed to work fine, and bulk loose boxed ammo didn't always function quite as well.
