Maxim Defense Ruger MKIV-SD Integrally Suppressed .22 LR Pistol with DeltaPoint® Pro

The Maxim Defense MKIV-SD Integrally Suppressed Pistol is redefining .22LR technology with tactical efficiency and stealth in mind. Inspired by the legendary MP5SD and powered by advanced M-Kore™ Technology, this platform transforms the iconic Ruger® Mark IV™ into a whisper-quiet precision tool. Designed with a porting system that reduces standard rounds to subsonic speeds, it eliminates first-round pop while improving accuracy, lowering recoil, and virtually removing muzzle flash. Whether you're operating in low-profile environments or refining your skills at the range, this fully serviceable, easy-to-maintain suppressor system offers unmatched performance in a sleek, bull-barrel aesthetic.
