"GAP" when referring to Glock refers to a caliber. A few years ago, Glock designed the .45 GAP (which stands for "Glock Auto Pistol" as a way to get a .45 caliber cartridge in a smaller frame gun. It was a failure. There is nothing wrong with the cartridge, but it just doesn't do much the .45 ACP won't do.
You'll need to be more specific - there are 5 pistol models that use .40 S&W rounds. They are: -Glock 22 -Glock 23 -Glock 24 -Glock 27 -Glock 35
