Real M9 manual of arms — plus a happy switch. The Umarex Beretta M9A3 Full Auto Blowback BB Pistol is an officially licensed Beretta replica that does two things at once: it's a credible training tool for owners of the real M9 / M9A3 firearm, and it's one of the most entertaining recreational BB pistols Umarex makes. With a flip of a switch on the right side of the hand guard, the M9A3 goes from semi to full auto.
Why it works. A 12-gram CO2 cartridge — held inside the magazine — powers each shot at up to 395 fps, and the blowback action cycles a real metal slide on every trigger pull, so the manual of arms feels authentic. The DA/SA trigger mirrors the firearm: a longer, heavier double-action pull on the first shot, then crisp single-action shots after the hammer is back. The drop-free 18-round magazine holds the BBs and the CO2 cylinder together, so reloads feel like the real thing. An ambidextrous safety makes it equally usable left- or right-handed.
And the "happy switch." The select-fire mechanism dumps the 18-round magazine in seconds — which is exactly the appeal. It's a memorable range-day experience, low cost per shot, and an easy way to introduce new shooters to recoil management in a controlled, low-energy setting. (And it's the right safety lesson — once you've experienced how fast 18 rounds disappears in full auto, the importance of muzzle discipline and a real backstop becomes very real, very fast.)
Notable features: FDE coloring (distinct from the all-black Glock 17 BB), metal frame for heft, and a 14mm counter-clockwise threaded muzzle — for mounting a cosmetic faux suppressor or a glow-in-the-dark tracer unit. Single magazine included.
Honest framing — this is not a self-defense product. A .177 BB pistol is for paper, plinking targets, and structured handgun drills. It is not a firearm, not a substitute for a firearm, and not appropriate for personal defense. Just as important: the M9A3 BB pistol is the size, shape, and ergonomic profile of a real Beretta M9A3.
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 only on private property you control, at a 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). Eye protection on, muzzle discipline always, finger off the trigger until on target, and store it secured and away from children. Treat it like a firearm in every habit that matters.
Best for Beretta M9 / M9A3 owners who want realistic at-home drill practice, recreational shooters who want a select-fire BB pistol for plinking range days, and anyone who wants a high-quality blowback BB pistol with a familiar Beretta DA/SA interface.
