The Ruger RXM pistol in 9mm with a black slide and gray frame and a 4.5-inch barrel (brand part no. 19443) delivers a striker-fired carry platform developed in partnership with Glock’s magazine compatibility ecosystem, in a slightly longer configuration than the standard RXM. Ruger builds the pistol with a 17+1 capacity and an optic-ready, serrated slide. A tritium front sight paired with a steel drift-adjustable rear sight supports low-light aiming, and an internal trigger safety rounds out the package. Two 17-round magazines ship with the pistol. Among optics-ready semi-auto handguns, this RXM 4.5-inch configuration favors shooters who want a slightly longer sight radius.
