FN 545 MRD QD Compensator Pistol, .45 ACP, 15-Round, Black

The FN 545 MRD QD Compensator pistol in .45 ACP with 15-round magazines and a black finish (brand part no. 66102135) pairs a quick-detach compensator with an optic-ready slide for reduced muzzle rise and fast follow-up shots. FN America machines the 4.1-inch barrel with an optic-ready, serrated slide, and fixed night sights back up a mounted red dot for low-light aiming. The non-manual safety design keeps the trigger clean for a fast presentation, and two 15-round magazines ship with the pistol. Among compensated semi-auto handguns, this 545 MRD QD Compensator configuration favors .45 ACP shooters who want reduced recoil for faster splits.
