The GLOCK 34 Gen5 MOS features an extended barrel and greater slide dimensions, making it a favorite among sport shooting competitors.
Design enhancements include the GLOCK Marksman Barrel (GMB) which delivers increased accuracy with enhanced polygonal rifling and an improved barrel crown, no finger grooves, ambidextrous slide stop levers for better versatility and control, and an nDLC finish, which is a tougher and more durable finish that is exclusive to the GLOCK manufacturing process.
