Walther’s tactical PPQ M2 SD .22 is the best of both worlds, combining the smooth-shooting, ergonomically-enhanced components of the PPQ with the fun and cost savings of 22 rimfire. This pistol has a polymer frame with an integral Picatinny MIL-STD-1913 rail, a reversible magazine release button, ambidextrous slide stop, and interchangeable backstraps for the perfect fit. It utilizes a quick defense trigger, matte finish Tenifer-coated slide and barrel for corrosion resistance. It has two drop safeties as well as a firing pin block. The PPQ M2 SD .22 has a 4.6 threaded barrel and is available with a 10+1 or 12+1 capacity.
