Although Glock’s lineup of handguns features mostly impressive firepower – enough to get the job done in so many instances – some law enforcement officials in the late 1990’s-early 2000’s found that Glock’s standard issue 9×19 pistols, such as the Glock 17, 19, 26, or 43, were not adequately taking down criminals. This led to a bit of a conundrum on the part of Glock, in that the company was faced with the decision to either concede that its existing handgun line wasn’t up to par for some officers and develop/adopt a new caliber, or ignore the pleas for a more powerful Glock. Glock settled on the former, and the result we ended up with is the Glock 37, a .45 G.A.P. (Glock Automatic Pistol) using cartridge developed to match the power of the .45 Auto guns while maintaining a compact form factor and high ease of use.

The .45 GAP, while offering the same power as the .45 ACP, is made shorter in order to fit a compact handgun. This is because Glock had no intention of drawing a contrast between the G37 and their other, more compact handguns, or invite comparisons to the .45 Auto Glock models – the 21, 30, and 36. The Glock 37 was a monumental achievement in that Glock continued to combine impressive stopping power and compact form, this time on an even greater level – it’s not tough to see why the New York State Police Department adopted the gun shortly after its introduction to the market. You’ll understand the greatness of the Glock 37 as well after reading this, our Glock 37 Gen 4 Review!
