A popular option for concealed carry, the GLOCK 26 Gen5 MOS features the GLOCK Marksman Barrel (GMB), delivering increased accuracy with polygonal rifling and an improved barrel crown. Other features include the removal of the finger grooves and an ambidextrous slide stop lever. The slide in MOS configuration makes it easy to mount a reflex sight on the pistol’s slide without the need for a new slide or separate mounting system.
