The G27 is Glock’s Gen 3 subcompact .40 S&W, part of the Baby Glock line. This example retains the Gen 3 frame profile with finger grooves and no accessory rail, plus rear slide serrations for traction.
Steel tritium night sights are installed, with H3-marked front and rear units. The original OEM sights are included, offering the option to revert to factory configuration.
It uses Glock’s striker-fired Safe Action system and short-recoil, locked-breech operation with a dual-recoil-spring assembly. Controls include a left-side slide stop lever and a small, non-reversible magazine catch.
Capacity is 15+1 with the included 15-round .40 S&W magazine, and the platform is compatible with higher-capacity .40 S&W Glock magazines. The 3.43-inch barrel and subcompact frame keep the package small without sacrificing chambering.
Markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." The slide and frame share matching serial number ECV464, while the barrel hood is stamped "40" with no serial, and the pistol ships with a Glock factory hard case bearing a matching serial label.
