PX4 sub compacts....
For pocket carry, I'd buy a DeSantis Nemnesis. For belt or holster carry check HighNoon Holsters, Galco, COM Holsters, Blade-tech, Kramer Leather, Ken Null, Safariland.
Kydex rigs are good. HighNoon Holsters sells a man made type leather holster that fits the PX4 sub-compact. It's a good value.
