As I was trying to decide what to write about first in the new year I thought "why not write about what I'm carrying right now?" Ah, a small Glock in the maligned .45 GAP caliber. I'm sure that everyone knows the story that the .45 GAP was born from Glock's realization that Americans love the .45 Caliber but their .45 ACP pistols were built on their 10mm frame causing their .45's to be larger than they needed to be.
The Glock 39 is a semi-automatic small-frame pistol chambered in .45 GAP. The G39’s cartridge, .45 GAP, is a shorter version of .45 ACP and offers comparable stopping power. However, the cartridge was specifically designed for compact pistols like the G39.
I recently bought a use Glock 39 from the pawn shop. It looked so new, i couldnt believe they only wanted $360 for it. honestly, i saw .45, sub compact, so i bought it. I had no clue what GAP meant nor that it was different from .45 ACP. When i went to buy the ammo, thats when i realized the difference between the two rounds. However, they didnt have any GAP ammo. Tough round to find in some places. Finally i found some at Gander mountain. I fired 50 rounds, and i did not like the gun because of the short grip. my pinky would hang off and the recoil was insane. So i did a little research, bought me a PX-39 magazine extension, fired another 150 rounds, and i fell in love. You can get the .45 GAP ammo on the internet thru luckygunner.com Great GREAT gun, s long as you but the magazine extension grip. Otherwise, hard to crontrol with the wicked recoil for a sub compact
