The Safariland 537 GLS Open Top Belt Slide holster (brand part no. 537-219-61) is molded for the Smith & Wesson M&P in 9mm and .40 caliber, built for right-hand carry with Safariland’s Grip Lock System (GLS) retention. The GLS automatically secures the handgun once holstered and releases with the middle finger during a standard shooting grip, giving a more intuitive and safer release than a manual thumb-break or hood. Its soft, flexible holster body is designed to mold around the wearer over time, while a tension adjustment lets shooters tailor the fit to personal preference, and it’s built to fit 1.5 inch (38mm) belt widths. For M&P 9/40 owners who want retention security without sacrificing draw speed, the 537 GLS is a proven Safariland design.
