The SD submodel equips the WMP with a 4.9 inch threaded barrel cut 1/2x28 TPI and polygonal rifling, pairing rimfire magnum performance with easy attachment of compatible 1/2x28 muzzle devices. The slide features front and rear serrations, purposeful lightening cuts, and a factory optic cut with the cover plate installed.
Controls are tuned for versatility. Walther's Quad Release system provides both ambidextrous paddle levers and push-button magazine releases, and the hammer-fired, fixed-barrel blowback action is designed for reliable cycling with .22 WMR. The fiber-optic front sight (red/orange) and a serrated black rear notch offer a bright, uncluttered sight picture.
The full-size polymer frame in black carries aggressive grip texturing with finger grooves and a full-length MIL-STD-1913 accessory rail on the dust cover. Overall dimensions are 8.6 in long, 1.48 in wide, and 5.66 in high, with a factory-listed weight of 27.8 oz.
