Looks like a Tomcat with special sights and a holster.
I had two of them. Be wary until you know, for sure, that they've worked the kinks out of the design. Many, many Tomcats were real problems early in their production. (The reason I had two was that the first was replaced under warranty; also had a number of busted firing pins, even though I used a snap cap.)
(Also look at the Kel-Tec P11; its about an inch longer, a hair narrower, a little higher, and 3 oz. heavier -- but it holds 10 rounds (plus 1) of 9mm. I've had both, and much prefer the P11. The slight increase in size seems like a small price to pay for 3 extra rounds and a much more powerful round.)
