The Springfield Armory XD Mod.3 OSP brings the third generation of the XD series to shooters who want a versatile 9mm Luger pistol for range work, home defense, or duty carry, featuring a 4" hammer-forged Melonite steel barrel with a 1:10 twist and a forged, Melonite-finished optic-ready/serrated slide that accepts popular red-dot footprints while offering aggressive serrations for confident slide manipulation. The striker-fired action delivers a consistent flat-face trigger pull and clean break, complemented by a tactile loaded chamber indicator, striker status indicator, and passive grip safety for layered security, and the aggressively textured polymer frame with Picatinny rail gives rock-solid purchase and accessory options. With a 16+1 capacity, dual captive recoil spring and full-length guide rod for reliable cycling, fiber optic front and white-dot rear sights for quick sight acquisition, a 1.2" grip width and a balanced 27 oz weight and 7.3" length that handle well on the draw, the XD Mod.3 suits training, competition, and defensive roles. Note that this is a firearm requiring FFL transfer; Springfield Armorys reputation for rugged, user-focused pistols makes this model a go-to for shooters seeking an optics-ready, duty-capable handgun.
