Type: BB blowback air pistol. Manufacturer: Umarex. Model: Makarov Ultra. Materials: Mostly metal with a few plastic parts. Weight: 1.5 pounds. Barrel: 3.5 inches, metal non-rifled. Propulsion: CO2 x 1. Action: Semi auto, single action only. Ammunition Type: 4.5mm steel BB's. Ammunition Capacity: 16-17 round full size drop out magazine. FPS: 350. Umarex really addresses the majority of the shortcomings found on the original non-blowback 4.5mm Steel BB shooting Makarov. They added the much asked for blowback operation, made the slide catch/release operational, upgraded the magazine to a full size drop out CO2 and BB magazine, gave it a more realistic paint job and even replaced the plastic safety with a metal safety. The only tradeoff is the loss of the short take up single action trigger and perhaps a few fps. All in all a big improvement over the first version which even today is still a very good BB pistol.
