With the release of the GLOCK 27 Gen5 in 40 S&W, the Gen5 family gets a new member. The innovative Gen5 design changes are added to this small, light, accurate, and powerful pistol that so many U.S. law enforcement agencies have chosen as their official backup weapon. By applying the Gen5 technology, this model comes with nDLC finish, a flared mag-well, the proven GLOCK Marksman barrel (GMB), and an ambidextrous slide stop lever. Adjustable like the Gen4 mode,l the subcompact frame of the G27 Gen5 features the modular backstrap and beavertail system (MBS) and comes with a reversible magazine catch to accommodate left and right-handed operators.
