It is practically the veteran among the GLOCK pistols, with which it all started: Originally equipped with a 9 mm caliber, the licensed replica fires both 4.5 mm pellets and steel BBs and is a lot of fun with around three joules. The heavy metal slide not only looks high-quality, it also ensures a decent weight. Thanks to the blowback, every shot is like a shot from the "real one" and the GLOCK 17 cuts a fine figure with its rifled barrel when it comes to precision. The GLOCK 17 is a real collector's item and, with its original GLOCK case, a must-have for all fans.
