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 a flared mag-well, the proven GLOCK Marksman barrel (GMB) and an ambidextrous slide stop lever. Adjustable like the Gen4 model 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. Note: The slide width of the 40 S&W Gen5 models is slightly bigger compared to the previous generation. Please consider when choosing your holster.

With the G17 Gen5 MOS GLOCK enhances the already near-perfect Gen5 model of "The original" with the addition of the Modular Optic System (MOS). The slide is precision machined to provide a mounting system for popular optic sights. With multiple adapter plates, you can quickly and easily mount miniature red dot sights to the rear of the Gen5 GLOCK slide, which has front serrations for easier and quicker manipulations. All of the Gen5 qualities are present in this standard-size pistol: The latest GLOCK nDLC surface finish, unmatched in hardness and rust resistance; the high traction Gen5 frame texture, quickly reversible magazine catch, ambidextrous slide stop lever, the GLOCK Modular Backstrap System (MBS) for individual operator adjustability, the universally-acclaimed GLOCK Safe Action^® System and high visibility orange magazine followers.
