Umarex Colt M1911 A1 — 4.5 mm CO₂ Replica Pistol
The Umarex Colt M1911 A1 4.5 mm replica delivers the classic look and feel of the legendary M1911 in a reliable CO₂-powered package. Lightweight yet solid in the hand, this pistol pairs an extremely easy-to-pull trigger with precise pellet performance to give shooters consistent, first-class results for plinking, training, or collection display.
Built by Umarex — a long-established leader in licensed firearm replicas — this model balances authentic styling (slide, grip and controls) with modern airgun convenience: an 8-shot magazine fed by a 12g CO₂ capsule, adjustable sights for better accuracy, and a compact overall length that feels familiar to shooters used to the original ordnance pistol.
