History of 45 GAP Ammunition
The .45 GAP (Glock Automatic Pistol) has been available since 2003, it is the first cartridge that has been introduced with the Glock name. The reason behind the development of this cartridge is that Glock wanted a .45 caliber bullet in a case that would not exceed the 9mm or .40 S&W. The point was that it would not be so long that it would have to have a grip larger than the Model 17 or 22.
The case of the .45 GAP is shorter than the .45 ACP, so much so that it is actually shorter than a 9x19mm! It uses small primers exclusively. All other case measurements are essentially the same. The bullets are the same as a .45 ACP, with most bullet weights ranging from 165 to 230 grains. The cartridges normally generate between 400-500 foot pounds of energy, with some loads touching 600 foot pounds of energy.
The reasoning behind the development of the .45 GAP was to develop the same or better energy as the .45 ACP while decreasing the front to back distance of the grip as well as the width of the grip. This made the .45 caliber handgun more accessible to shooters of smaller stature.
The .45 GAP was somewhat popular during its initial introduction. A few firearm manufacturers outside of Glock produced .45 GAP pistols. Currently, Glock is the only one that continues production. The best reception of the .45 GAP has been in the law enforcement community. The power of the .45 ACP in a more compact frame has made the Glock 37, chambered in .45 GAP the choice for five state law enforcement agencies. The New York State Police replaced their 9mm Glocks with the .45 GAP, while the state agencies for Georgia, Pennsylvania, South Carolina and Florida have all replaced their .40 S&W pistols with the Glock 37.

" I'm in no way an expert but I've fired 100 rounds of this ammo so far and am pleased with my purchase 4 inch grouping at 10 yards with my glock 37 which isn't bad for a 45. The ammo does smoke a little but there were no misfires, jams or duds. "
