The most realistic at-home practice you can get with a BB. The Umarex GLOCK 17 Gen 4 Blowback BB Pistol is an officially licensed Glock replica built for training and recreational shooting — same grip texture, same controls, same Glock ergonomic interface as the Gen 4 firearm, in a CO2-powered .177 BB airgun. For Glock owners, it's a way to drill the fundamentals — sight picture, trigger control, magazine changes — at home, on your schedule, and without firearm-range ammo costs.
Why it works. A 12-gram CO2 cartridge powers each shot at up to 320 fps, and the blowback action cycles a real metal slide on every trigger pull, so the manual of arms feels authentic — including the last-round hold-open (the slide locks back when the magazine is empty, just like the firearm). The drop-free 18-round magazine holds the BBs and the CO2 cylinder in a single unit, so reloads feel right too. Field-strip capability lets you break it down for cleaning the same way you would the firearm.
What you're getting. A faithful Gen 4 replica with fixed Glock-style sights, a manual safety, and the iconic Glock interface and grip texture. Steel BBs only. Includes one magazine.
Honest framing — this is not a self-defense product. A .177 BB pistol at 320 fps is for paper, plinking targets, and structured manual-of-arms practice. It is not a firearm, not a substitute for a firearm, and not appropriate for personal defense — there are purpose-built tools for that. Just as important: this pistol is the size, shape, and color of a real Glock 17.
Never carry it concealed, never draw it in public, and never display it where someone (a bystander, a homeowner, or police) could mistake it for a firearm. Use it on private property you control, at an indoor or outdoor range that allows BB pistols, or in a dedicated training space.
Legal & responsible use. 18+ to purchase. Air-pistol laws vary by state and city — Umarex specifically notes this item may be restricted in some areas (we enforce that at checkout). Always wear eye protection. Treat it like a firearm: muzzle discipline, finger off the trigger until you're on target, know your backstop, store it secured and away from children.
Best for Glock owners who want realistic at-home training, recreational target shooters, and shooters who want a high-quality blowback BB pistol with a familiar ergonomic interface. Free shipping on orders over $100; 30-day satisfaction guarantee.
