I put this here because I think titanium 5 shot .38 +Ps are smaller than most semi auto handguns, but if you can think of a semi auto that would suit my needs I'm all ears.

I am looking for something that is in a decent caliber that I can conceal wearing almost nothing. I want something that will easily fit in a pocket and not weigh it down. I want something tiny. I want to have this gun on me when I go to the beach in board shorts and not have anyone bat an eye at the huge bulge. A true "Concealed is concealed" gun.

This isn't for daily CCW. I'm not concerned about being outgunned or only having five rounds as this will only be used when it is physically impossible to carry anything bigger.

Is a Titanium .38 special (made by whom?) my best bet?
