The Grendel P30 is a semi-automatic pistol chambered in .22 Winchester Magnum Rimfire.

Designed by George Kellgren and manufactured by Grendel Inc., it uses a 30-round Zytel magazine and was available with a 5 or 8 inch barrel.

A carbine version (R-31) was also offered.

The P-30 uses a straight blow-back operation, with the assistance of a fluted chamber to reduce case friction during extraction.
