Question on Glock Ammo?

A former firearms student of mine texted me that he has a dozen boxes or so of Speer 200gr. for sale.
He also used a term, they are of 45 gap made exclusively for the glock 45,37,38 and 39. And, the Springfield EMP 45.

Does anyone know what he’s talking about? Is this just regular 45 ammo? I’ve claimed to be the Jarvis/Vision of firearms, I’m always looking to learn. :slight_smile:

.45 G.A.P. is a variation of .45 Family.

And these Glocks are made for this ammo:

Well that answers that. So they made a very specific ammo just for a few specific firearms. I did not know that. Thanks Jerzy.

The .45 GAP has the same diameter as the .45 ACP pistol cartridge but is slightly shorter, and uses a small-pistol primer instead of the large-pistol primer most commonly used in .45 ACP ammunition. Originally, the maximum bullet weight of the .45 GAP was 200 grains (13 g). In order to provide terminal ballistics that matched the standard 230-grain (15 g) .45 ACP loads, the .45 GAP was designed to operate at a higher standard pressure—roughly equivalent to the higher pressures found in .45 ACP “+P” rounds. Since the .45 GAP has a much smaller cartridge volume than the .45 ACP, the desired pressure and resulting velocity needed to be achieved through powder selection alone. Later development concluded that the .45 GAP could also fire 230-grain (15 g) projectiles, as does the .45 ACP; though this pushes the .45 GAP cartridge to its limits.

You are welcome…

There are so many different ammo sizes that I had to think for a minute to find out this one…

It just find it amazing that companies try/tried to make their firearms so proprietary that there certain odd calibers would only work in them.

I have a stupid little Beretta Tomcat, that uses a .32acp… and that was always darn hard to try and find any ammo for it when I used to shoot it. At cabelas, there’d be like 15 feet of shelving dedicated to 9m and 40 and they’d maybe have 3 boxes of .32ACP.

Being able to somewhat standardize is also a + on a battlefield, being able to use your ammo with a picked up firearm or vice versa.

The .45 GAP (Glock Automatic Pistol) was a solution in search of a problem. The intent was .45 acp performance in a 9mm size pistol. It was a rousing failure. While it worked ok (as expected of a Glock). Most .45 folks just stayed with the ACP. Ammo was/is rare and tended to be pricey. Wasn’t around and being marketed long.,
