Kel Tec has come a long way in terms of reliability and I know more than a few officers that carry them. Nothing wrong with having an extra bullet launching platform on your person.
When the airlight pistols from S&W came out and I got one I don't think I will ever looked back. I carry the S&W 442 as a back up and off duty when I feel like walking light.

I carry either the Cor-Bon ammo 110gr +p DPX (Possibly the best load offered for a 38spl +p period) or the Cor-Bon 100gr +p PowerBall ( possibly the 2nd best round in a 38spl period).
Both these loads come out a short barreled weapon at amazing speed with very light recoil and offer over 12" of penetration into meat. Exactly what you need to calm an attacker down.
