Best weapon for Concealed Carry advise

While I don't know anything about that model I will say my sister has a KelTec 22lr that jams on every ammo.

The Walther P22 has the same issue. The tip of an unjacketed 22 hits the top of the barrel as the feed ramp is super steep pushing the tip up. Darn thing will only be nice when shooting copper jacket 22... no way, would I carry it CCW.
