This Walther PPQ M2 has a number of features that enhance your shooting accuracy. This Walther PPQ M2 enhances the feature of firing pellets with a blowback slide. Realistic recoil is combined with maximum precision. Unlike many other models, the PPQ M2 feeds the 4.5 mm pellets from its magazine by means of a chain. Besides accommodating a 12 g CO? cartridge, the magazine has space for 21 rounds. The slide jumps back with every shot, producing a strong recoil. A rifled barrel ensures tight groupings. In appearance, this CO?-powered airgun cuts a good figure alongside modern service pistols, with original dimensions, a heavy metal slide and a polymer frame with a non-slip hi-grip surface.
