Lipsey's had Glock reproduce the original "Tupperware peel-top box" and enclose it in a commemorative magnetic closure box with all of the original accessories and a certificate of authenticity. Overall, GLOCK has really delivered with their latest generation of G19s. [12] The Glock 17 outperformed eight different pistols from five other established manufacturers (Heckler & Koch of Germany offered their P7M8, P7M13, and P9S, SIG Sauer of Switzerland bid with their P220 and P226 models, Beretta of Italy submitted their model 92SB-F, FN Herstal proposed an updated variant of the Browning Hi-Power, and the home-grown Steyr Mannlicher entered the competition with the GB). G47 standard size slide is interchangeable with G19 compact size slide.

Some newer rear sights can be adjusted for windage (on certain models due to the windage sights not coming as factory default), as it has a degree of lateral movement in the dovetail it is mounted in. The introduction of fourth-generation Glock pistols continued in July 2010 when the Glock 19 and Glock 23, the reduced size "compact" versions of the Glock 17 and Glock 22, became available for retail. These first-generation adjustable rear sights extended past the slide and were susceptible to breaking. It’s not apparent if these Glocks were intentionally left unmarked, or if they were not caught during Glock’s exhaustive quality control checks. The stabilization of the round is not by conventional rifling, using lands and grooves, but rather through a polygonal profile consisting of a series of six or eight interconnected noncircular segments (only the .45 ACP and .45 GAP have octagonal polygonal rifling).

The first two .380 ACP models are primarily intended for markets that prohibit civilian ownership of firearms chambered in military calibers such as 9×19mm Parabellum. The Tenifer treatment is applied in a 500 °C (932 °F) nitrate bath. It operates via straight blowback of the slide. Instead of using a traditional broaching machine to cut the rifling into the bore, the hammer forging process involves beating a slowly rotating mandrel through the bore to obtain the hexagonal or octagonal shape.
