The FN 309 MRD pistol in 9mm with a 3.8-inch barrel and black finish (brand part no. 66102378) is designed for reliable, everyday personal defense, built around an internal hammer-fired operation for a crisp, light trigger pull. FN America gives the pistol effortless slide-racking force and easy-loading magazines, and multiple internal safeties include a no-trigger-pull takedown feature. The slide is optic ready, compatible with red dot optics sharing the Leupold DeltaPoint Pro or Shield RMS footprints, and both a 16-round and a 20-round magazine ship with the pistol. Among optic-ready, internal-hammer semi-auto handguns, this 309 MRD configuration favors defensive carry shooters who want a crisp trigger and broad optic compatibility.
