The Gen4 package brings functional upgrades including the dual recoil spring assembly, an enlarged reversible magazine catch, and the Modular Backstrap System. The grip uses the Gen4 rough-textured surface with finger grooves; no backstrap is installed, and the full MBS kit is included.
The 3.43-inch cold hammer-forged barrel uses hexagonal rifling with a right-hand 1:9.84 twist, optimized for .40 S&W. Sights are the factory fixed polymer set with a white-dot front and white-outline rear, providing a 5.39-inch sight radius.
Built on a durable polymer frame with a matte black slide, this striker-fired, short-recoil, locked-breech pistol uses Glock's Safe Action system with a 5.5 lb trigger. The subcompact G27 profile omits an accessory rail for a streamlined form factor.
Markings and proofs include the "27 Gen4" and "40" slide rollmarks, the "GLOCK AT" barrel hood mark with pentagon proof, and the "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." import mark. This is a discontinued commercial model, offering distinctive Gen4 features and Austrian manufacture.
Capacity is 9+1 with the included three factory 9-round magazines for .40 S&W, providing a complete range-ready setup.
