Difference between ACP and GAP (new to board :D)

[darkreaper2828]

Hey everyone!

Been a big Glock fan ever since I was a child. Recently purchased my very first handgun, the Glock 21. About 7 days left on the waiting period and I'm absorbing as much info on Glocks as I possibly can. Now, I know it takes .45 ACP ammunition but what exactly is the difference between ACP and GAP? Can I use GAP and ACP ammo in my Glock 21? If so/If not, where on the ammo box does it list GAP or ACP? Recently picked up a box of 50 rounds and I just want to confirm I got the correct ammunition ^_^;;
I look forward to your responses!

welcome, my friend,

GAP has a shorter length shell. it's loaded to +p .45acp pressure so i can achieve the same velocities. this also means there cannot be a +p GAP round. the shorter shelled GAP was made in order to fit a 45 caliber round into a 9mm/40cal size grip.

you CANNOT use GAP in your G21. you want the 45 ACP ammo for your G21. excellent gun, by the way!


(GAP/ACP)




most 45ACP ammo just says "45 auto":







you DON'T want this:

Ah, alright. Thanks very much for your input it helps a lot. Now I'm pretty sure I got the correct ammunition, but for the sake of double checking (and peace of mind) would you mind checking out the picks I took of it to reaffirm my speculation

yep, you got the right stuff! that federal champion 45acp is what i shoot in my 1911's. good quality stuff (and cheap as dirt at Chinamart lol).

haha, my buddy uses fed champ in his glock 23 (awesome gun) and for the low low price of 14 bux I couldn't resist. thanks again, I'll be picking up more of these when they restock :P

i know! i've only found one box of 45acp champion at my local chinamarts in the last year lol. they always have a buttload of 40cal champion though....can't beat their prices!
