The KWC Guerrilla Police PT92 Air Pistol - 4.5mm is styled after many modern blow back pistols this means it functions very similarly to the real steel. It is a very hefty gun made almost entirely from metal and has a very snappy blow back action which adds to its shooting realism. Even the magazine looks and feels like a real 9mm magazine with similar weight and dimensions. The Guerrilla Police shoots very accurately for a BB airgun and has fairly decent power considering its blow back function this does result in heavy usage of CO2. Nevertheless, this is a must-have replica air gun for many reasons price realism all metal design and performance.
