I've had my eye on a CZ for a while, but yes, a little too big for what I'm wanting. I already carry a PX4 compact, but wanting something a bit smaller for pocket carry. If I could find one I would love a PX4 sub-compact, but no body has them anymore.The CZ 75 compact models are great litte DA/SA 9mm guns, but I wouldn't call them sub-compacts. They may be a little bigger and heavier than you're looking for. They're roughly the size of a G19.
