S&W Bodyguard 380 in an Uncle Mike's pocket holster ($320 total)

Fits perfect in front pocket and nobody will ever know its there.

I have several of the pistols already mentioned but none are as convenient to carry as the bodyguard. It's shoots plenty good enough to handle someone close enough to actually be a threat. If they are still standing after 7 rounds then I guess it's just my time.

You're only as good as your worst shot-
