The longer slide provides a longer sight radius and reduced felt recoil compared to the G21. Built for USPSA Single Stack and IDPA ESP competition use. The combination of .45 ACP power with Glock reliability and the MOS optic mounting system made it popular in competitive shooting before the proliferation of red dot-equipped striker pistols.
