Blue Line Global Mauser M20 SD 22 LR 4.75" 10+1 DA/SA Semi-Auto Pistol

The Blue Line Global Mauser M20 SD is a rimfire pistol chambered in 22 LR, built around a double/single-action trigger with an ambidextrous decocker. A 4.75" threaded barrel sits beneath a machined aluminum slide, paired with a polymer frame finished in black. The M20 SD tips the scales at just 1.4 lbs unloaded and stretches 7.8" overall, giving it a light, easy-handling footprint for range sessions and casual plinking.

Cycled as a DA/SA semi-automatic, the M20 SD feeds from a 10-round detachable magazine for relaxed trigger-time training, small-game hunting, and affordable target practice. The threaded muzzle opens the door to a suppressor or compensator, while the classic double/single-action layout delivers a smooth, deliberate first shot followed by lighter, crisper follow-up pulls. Blue Line Global designed the M20 SD as a versatile rimfire pistol that bridges training, target, and varmint roles in a single, lightweight package.
