I don't like ankle carry either. I feel it is slower than pocket carry and it is MUCH MORE OBVIOUS you are going for a gun. If you get a wallet holster for your mouse gun, the bad guy may just think you are about to hand him your wallet. Check out thess holsters.
I pocket carry a Kahr PM9 in a Desantis Nemesis holster. I changed the profile to accomodate my Crimson Trace Laser. I just carry my wallet over the front of it and no one notices a thing. If you pocket carry, you HAVE to wear pleated pants. Darker colored pants are also much better for concealment.
