The subcompact Glock 27 was similar in respects to the Glock 26, designed for ease of concealment while retaining the accuracy and firepower of their bigger Glock cousins. What differentiated the G27 from the G26 was its chambering for the .40 S&W cartridge popular with American security and police personnel. Introduced in 1996 alongside the Glock 26, the Glock 27 offers the same dimensionally small size, fitting comfortably in the palm of the average hand while allowing the user to conceal the pistol in places such as an ankle holster - making it the perfect backup weapon.
Externally, the Glock 27 mimicked the fine lines of the Glock 26, complete with its shortened frame and pistol grip. The grip featured an ergonomic hold as well as an integrated trigger guard with a forward finger rest. The slide was designed in typical Glock fashion and offered a forward and rear sight. The firing action was blowback/double (safe action) with a trigger pull of about 5.5lbs. Length of the weapon topped off at 160mm (6.29 inches) with a barrel of 106mm (4.17 inches), the latter featuring a right hand twist. Weight was 19.75 ounces with a loaded weight of 26.98 ounces. Width was just 30mm (1.18 inches).
The standard available magazine allowed for 9 cartridges. However, this could be upped by way of the optional 11-, 13-, 15- or 17-round magazines as desired.
