The P-10 is a very unique semi-automatic pistol manufactured by Grendel from 1988-1991. The firearm is a double-action only, blowback-operated pocket pistol that is chambered for .380 ACP rounds. The most notable feature of this pistol is the lack of a detachable magazine. Like most other modern semi-automatic pistols, the rounds are kept within the grip of the pistol however; rounds are fed in from the top of the gun, similar to rifles such as the M1 Garand. By sacrificing the use of a detachable magazine, this pocket pistol carries is afforded the ability carry 10 rounds, plus one in the chamber. Due to the ease of use and high capacity for a pocket pistol, the Grendel P-10 has found success in the personal-protection market among both skilled and unskilled gun carriers.
