Action: Single & Double action Ammo Type: 4.5mm steel BBs and /177 caliber Pellets. Ammo Capacity: 8 rounds. FPS: 420 Here's what we know for now! The Umarex SA10 has a metal frame and polymer slide, it shoots both .177 caliber pellets and 4.5mm Steel BB's. The Umarex SA10 CO2 Blowback Pellet and BB Pistol has blowback action with a single and double action trigger and sports a full size drop out metal magazine that holds the CO2 and removable rotary 8 round magazines, 4 in total 1 ready for shooting and the other 3 on standby ready to be hot swapped. We should expect around 400 fps with lighter ammo and I am hoping for decent accuracy using pellets since the Umarex SA10 CO2 Blowback Pellet and BB Pistol does have a rifled steel barrel.
