I have a couple Kel-Tec handguns already.
The PF-9 is a semi-automatic, locked breech pistol, chambered for the 9mm Luger cartridge.
The P-3AT is a very compact, semi-automatic, locked breech pistol, chambered for the .380 Auto cartridge.
Now I have my eye on the PMR-30. The PMR-30 is a light weight, full size pistol chambered for the flat-shooting .22Magnum cartridge (.22WMR). The PMR-30 operates on a unique hybrid blowback/locked-breech system. This operation system allows for the use of a wide variety of ammunition as it seamlessly adjusts between locked breach and blowback operation, depending on the pressure of the cartridge. It uses a double stack magazine of a new design that holds 30 rounds and fits completely in the grip of the pistol.
--Costs about $300. Cheap enough to risk it!
