The Springfield Armory HC PRO CMP UDT 3.7 (model SPG HCP9379BOSPCOMPPAC) is a compact, duty-capable 9mm handgun that blends concealment-friendly footprint with range-ready features for carry, duty, and competition use, and it requires FFL transfer. The optics-ready billet machined slide with an integral compensator and Melonite finish gives the pistol reduced muzzle rise and durable corrosion resistance, while the 3.7" hammer-forged barrel with 1:10 twist delivers consistent accuracy out to defensive and practical distances. A factory-installed Viridian RFX11 green dot with Instant-On and long runtime provides fast, intuitive aiming in low light encounters, and white-dot front with Tactical Rack U-Dot rear sights give a co-witnessing option for shooters who prefer iron backup. The black polymer frame with Adaptive Grip Texture and a 1" grip width offers secure control for rapid follow-ups, and the dual captive recoil spring with full-length guide rod smooths felt recoil for better shot-to-shot recovery. Weighing roughly 21 ounces and measuring 6.6" long, this HC PRO Compact UDT model is aimed at users seeking a lightweight, controllable carry gun that handles defensive scenarios, concealed carry, and action pistol training with modern optics and compensator advantages.
