Umarex SA10 — Dual Ammo CO2 Blowback Pistol

Umarex SA10 Review — An Innovative Design

The Umarex SA10 is a CO2-powered blowback pistol with a truly unique design. The drop-out magazine holds both a 12g CO2 capsule and three spare 8‑shot ammo rotors . You can shoot .177 pellets or 4.5mm steel BBs — even mix them in the same session . The heavy metal slide combines with a durable polymer frame to give an authentic weight of 924g . Cutaway view ports in the slide reveal a striking gold-coloured barrel . The threaded muzzle accepts silencers or compensators, and the underside Weaver rail lets you mount lasers or torches .

Umarex SA10 UK — Specifications and Performance

The SA10 produces 130 m/s (427 fps) with an energy output below 3.5 Joules . You get approximately 60 shots per CO2 cartridge, dropping to 40-50 shots in cold weather . The blowback action delivers strong, satisfying recoil with each shot . Owners consistently praise the realistic weight, solid construction and excellent balance for two-handed shooting . One detailed comparison test found the SA10 remarkably accurate for a blowback pistol, achieving tight groups at 10 metres with RWS CO2 Target pellets .

Umarex SA10 Magazine — Storage and Loading

The innovative drop-out magazine stores three spare 8‑shot rotors inside the grip . This means you carry 24 spare rounds plus the 8 already in the gun before touching your pocket . The rotor storage is a fantastic idea, though some owners find the fit a little loose . A simple modification using small strips of self-amalgamating tape tightens the storage slots and prevents rotors dropping out during handling . The pistol operates in both single and double action modes. Cock the slide for a lighter single-action trigger pull, or fire repeatedly in double-action .

Umarex SA10 Silencer — Threading and Compatibility

The threaded barrel accepts muzzle accessories, but the thread pitch is proprietary and not 1/2 inch UNF . Standard airgun silencers will not fit without an adapter . The SA10 can be very quiet with a correctly fitted custom silencer. However, owners warn that a poorly aligned silencer will cause pellet clipping and destroy accuracy . One forum member traced wild accuracy issues to an eccentric silencer, and the problem disappeared completely when he removed it . For best results, we recommend testing the pistol without a silencer first, then adding a custom-fitted adapter if you need noise reduction .

Umarex SA10 Problems — Honest Owner Feedback

The SA10 has several known issues worth discussing. The most serious reported problem is rapid accuracy drop-off after only a few shots, with groups opening up dramatically . In one case, attaching a 140-grain chronograph to the silencer inexplicably cured the issue, suggesting the silencer may be whipping during blowback . The trigger has an unusually long stroke before release, which takes practice to master . Owners find the safety catch positive but too stiff — you need a second hand to operate it . The plastic slide clip can also break, sometimes after just one day of use . The front sight lacks any coloured dot, making target acquisition slower in poor light. On the positive side, the SA10 is solidly built, looks great and delivers surprisingly good accuracy once you understand its quirks .
