Fmk G3 9mm 4.5" 17-Round Threaded Barrel Pistol

The FMK G3 9mm 4.5" 17-Round Threaded Barrel Pistol represents a purpose-built platform for shooters and professionals who demand versatility without compromise. Purpose-designed for duty, training, and tactical applications, this striker-fired 9mm combines a compact yet controllable 4.5-inch profile with a threaded barrel—enabling quick integration of suppressors, compensators, or muzzle devices. Whether you're outfitting a personal defense carry, law enforcement duty rig, or running suppressed drills on the range, the G3's 17-round capacity delivers the firepower and ammunition supply necessary for sustained engagement scenarios.

Built on FMK Firearms' proven polymer-frame architecture, the G3 provides a low-profile, ergonomic design that suits both standard and tactical grip preferences. The threaded barrel—factory-installed at 1/2x28 TPI (standard 9mm spec)—eliminates post-purchase delays and guesswork, allowing operators to thread a suppressor directly out of the box. The 4.5-inch barrel strikes a balance between muzzle velocity retention and handling speed; you retain meaningful ballistic performance while keeping the overall package compact enough for vehicle carry or inside-the-waistband deployment. The 17-round single-stack magazine capacity ensures you're not compromising round count versus footprint.

Law enforcement personnel, armed security professionals, and civilian operators seeking a duty or backup pistol will appreciate the G3's no-frills reliability and aftermarket accessory ecosystem. The threaded barrel design accommodates any standard 9mm suppressor or muzzle brake, making this platform ideal for shooters investing in sound reduction for training or tactical operations. The lightweight 1-pound frame recoils management and sustained accuracy during rapid-fire strings, while the compact dimensions ensure compatibility with most inside-the-waistband and outside-the-waistband tactical holsters. For shooters transitioning from or familiar with Glock ergonomics, the G3's consistent manual of arms facilitates rapid adoption.
