The 45 GAP was created for Glock to be used in the more compact 45's. The casing is necked down a little bit trying to give less recoil in a 45.

Gap stands for Glock Automatic Pistol and as USMC said it was created for Glock for the more compact pistols Glock manufactures.

The 45 GAP is basically a wimpy version of the 45 ACP. The only real difference is the GAP is shorter, resulting in a whole lot less power.

About 90 years. 45 ACP is still top of the 45 autos.

My 2 cents: Glock wanted their own name on a cartridge and S&W already has the 40.

I have Glock's models 21,22,and 37 GAP. I find the GAP ammo will shoot fine in the Glock 21. 45 ACP doesn't work in a Glock 37 though. The 45 GAP is like a glock 22 with more power, in fact in regular loads the GAP is a more powerful round than APC. The GAP is basically an improved ACP round. It uses the technology used in 40 SW and 10MM ie by using higher pressures the GAP can produce more power in a smaller package. I like both rounds. The ACP reloading dies will work with GAP ammo so there's no need to get new equipment to reload GAP. I haven't found it difficult to find GAP ammo, its all over. I get it online,or at BassPro and Walmart. I pay about fifty cents a round for GAP which is about the same as I pay for ACP. In fact, I pay less in GAP for a more powerful round because it's all +P to begin with. If I buy +P ACP it's $1.00 a round. I love all my Glock's, and the Glock 21 is a great gun, but so is the Glock 37 if you want a more modern gun. There all good, I wouldn't rule out the GAP. There are good reasons why many police forces, and the military, are buying Glock 37's. A light compact frame like the Glock 22 with the power of the 45 ACP. Sounds like a win-win to me.

The .45 ACP has been around for 105 years. The .45 GAP has only been around for about 7 years. It turned out to be one of those "great idea's" that didn't pan out. It was never really embraced by the shooting world and is dying out slowly. Finding the GAP ammo can be difficult at times while ACP ammo is never a problem. Stick with a proven cartridge...the ACP.
