Well, you've got a 30 round 22 WMR with fiber optic sites, rail mountable nicknamed the jam-o-matic. If you have a newer one you'll be fine. If you've got the original one maybe not so fine. It's a semi-blowback design so a strong grip will help compensate. Kel-Tec recommends CCI 40 grain Maxi Mag. As with other Kel-Tec pistols I would strongly recommend using the ammo they recommend.
