The Glock 17L is a competition version with a longer barrel and slide. Early versions ... had a ported barrel to combat muzzle flip. The 17L has been largely replaced by the Glock 34 due to post-introduction restrictions on overall length in many popular competition categories.

The Glock 37 is a Glock 17 modified to fire the proprietary .45 GAP round. It uses a different slide, frame, barrel and magazine but is otherwise similar to the Glock 17, having only a wider slide. It has a 10-round magazine capacity. The Glock 37 first appeared in 2003, and is mainly available in the U.S. It was designed for law enforcement and self-defense use where its large caliber offers superior single shot stopping power, while avoiding the large frame size problems of the Glock 21.

The Glock 17A is a variant produced for the Australian market, to conform to local laws regarding barrel lengths created after the Monash University shooting. The only differences between a Glock 17 and a Glock 17A is that the 17A has a 120mm long barrel which protrudes from the frame visibly and the magazine can only hold 10 rounds.
