Walther 1250 Dominator

4.5 mm (.177) Pellet, PCP, < 7.5 J

A classic is reborn! That’s the story behind the Walther 1250 Dominator. Walther’s engineers successfully installed the mechanism of the legendary LG300 Dominator in a compressed air repeating system with an 8-round rotary clip. The bolt action presses the pellet directly into the barrel, ensuring high accuracy and very low energy loss even at long distances. The 300 bar cylinder can deliver 100 shots at 40 Joules. The Dominator also cuts a good figure. Raised studs on the forearm and pistol grip ensure a firm grasp from a firing position. The ambidextrous Monte Carlo cheek piece on the fiberglass-reinforced synthetic stock will please both right-handers and left-handers.
