What is the purpose of the 45 GAP? I personally don't know anyone who has this caliber. Is this one of those calibers that will eventually go extinct?

To put .45 acp power into a package the size of a 9mm.  It is equivalent to a +P .45 acp.

Glock tried to put a 45 cartridge in a 9mm size gun.
It never caught on.

Some police agencies wanted 45.

But some (females especially) couldn't handle the larger size 45acp pistols grip size.

So, they made a 45 cartridge that fit into the smaller frame pistols.

Had the assault weapon ban stayed in place the 45GAP would have been a home run.  I believe Glock produced it thinking 10 round mags were going to be the norm.   They gave it away to police departments with a media blitz to get it going and when the assault weapons ban lapsed it became a dud.  Most of the agencies who went to it have dropped it and it will be like a .357 sig without the ability to swap out with a .40 barrel.

I owned all 3 of them and liked the 37 and 38.  When I started having a problem finding ammo I got rid of them.

It kinda sucks that you can't really trim 45acp brass down to use for reloading... it can work, but it has issues that make it far less optimal than buying proper brass: taper in the brass itself resulting in possible bulging, rim size, primer (small vs large) size, extractor grove profile, pressure and setback issues.

The 45GAPs I've shot have been great guns but ammo price and scarcity is even worse than my beloved 10mms.

Yup I like the way it shoots and it did some firsts for Glock that would be seen on future models.  Rounded slide nose, the trigger bar bump, and a pistol built as a 10 round gun for the AWB.  Had they slimmed the slide more it would have been even better I think.

Stupid question but are the GAP glocks dimensionally similar to the 9/40/357 or do they use the ACP slide width?

Because it's enough shorter that it will fit in the G17/19/22/23 frame pistols. The .45acp cartridge won't do that.

45acp brass = .898" if I recall correctly
45GAP = .760"
.138" is a pretty big difference in overall length

I assumed that it was the "girth" of the 45 that made it difficult to double stack not the length. why would a shorter bullet fit more in mag?

It isn't capacity that the 45gap addresses... it's fitting a 45 caliber bullet into that 9mm sized frame.  The limitation is front to rear in the gripframe / magazine, not side to side.  Capacity is certainly reduced vs 9mm and 40sw, but it effectively shoehorns a 45 into a 9mm frame which is a feat worth noting.

It's similar to the 40sw being a shortened 10mm... 40sw is the old FBI spec'd light 10mm load in a shorter case that Smith and Wesson said "Hey... we can put that into a smaller gun!!!".

If your local shop will order em in Vance Outdoors out of Columbus, Ohio had a pretty good stock of 10mm Glocks pretty recently and they're priced pretty fairly.
I ordered one from em and they had it shipped within 30 minutes of payment.  I timed it well... order in the que right before Fedex showed up for the daily pickup.

Was supposed to be a 45 fitting in the 9/40 frames and slides from glock.  They ended up with an abortion of a large slide like the other 45s and a 9/40 grip.

If Springfield ever came out with the 1911 EMP in .45 GAP  that was on the cover of the American Rifleman about ten years ago, I'd own one.  At the time I was really into .45 ACP guns and thought that particular  EMP would be the cat's ass for a carry gun since it was a 7/8th copy of a 1911 with similar ballistics.  Now, I've jumped on to the 9mm bandwagon, but I'd still be tempted if Springfield ever came through which is highly unlikely.  One of theit reps at SHOT told me the reason it never materialized is they couldn't get them to function reliably with that concept gun.

The cartridge is not a bad cartridge just it does not do anything that 9/40/357 do not already do except be lower capacity and same price as 357.  The cartridge is actually very accurate and case life is really good on it and you can use 45ACP reloading equipment to reload for it.

The GAP was created for people like me. I needed a 45 that fit my hands comfortably. I have one, but I don't care for 1911's as much as a Glock. I reload and with a little googling, I've got two five gallons of GAP brass that will last me for a long time.

It's also fun when I shoot a match and the brass whores swoop in to pick up the brass and look at  it and realize they can't use it. Most of the people I shoot with know it's mine so I frequently get it back. It's still fun to see that confused look on their faces when they realize it's not ACP brass.

Wrong.... .45 HP was designed for that long before .45 GAP existed. 

American Rifleman | The .45 HP Load
.45 GAP came about for two reasons.

1. To fit a .45 ACP ballistic equivalent cartridge into a Glock 9mm frame.
2. For Gaston Glock to have a carriage with his name on it. (Unconfirmed Rumor)

if limited to ten rounds in a G17 frame.... then get the biggest bullet out there.

Huh... learn something new everyday.
I seem to recall reading in Coopers Gunsite newsletters that the 10mm FBI spec 'light' loading was the parent of the .40sw... were they completely independent developments, or did one influence the other?  Was Cooper mistaken?

Either way... .40sw is my 2nd favorite auto-pistol cartridge right behind the 10mm.  .45acp and 9mm can duke it out for 3rd place.

When my buddies in PSP told me they were getting G37s I thought they were screwing with me.   It made no sense, as it was expensive and hard to get.  From what I was told the department wanted  a .45 but was concerned about female Troopers not being able to grip the Glock 21.  The department only kept them for a few years.

I think that is the .45 GAP came out in the early to mid 90s it would have cemented its place in the industry. I have about 500rd for the Speed Gold Dot 180gr JHP on moon clips for my Revolvers. Picked it up cheap and myn1917s and Model 25/625 love it. It is a Hell of a self defense cartridge. After I snag me a G31 and G33 maybe I'll hunt down a cheap G37 and G39. I carried a G37 for a little bit in uniform.

Our local PD went to the 45 GAP when it came out.  They quickly abandoned the round and went back to 45 ACP.  I have a lot of friends on the PD and SD, but nobody would give a solid explanation.  The best answer was "ammo cost and availability".  As a result, the officers and deputies could buy the the GAPs fairly cheap.  I ended up with one, and never warmed up to it (or the ammo cost).  It was sold.  Later I sold all of my "big bore" Glocks (40 and 45 ACP) EXCEPT for my 10mm.  Later still I sold my two 10MM Glocks.

I definitely not a Glock hater (my wife and I both EDC Glock 9mms, but I also like to carry HK 9/40/45s).  For me, Glock is probably the best overall 9mm, but I didn't care for the larger options.  I prefer HK for all things 40+.  All told, I've been carrying Glocks since the early 1990s.  The 45GAP was the absolute worst of the lot (the second being the G36).

I never cared for the round either but I've seen the bullet after it's been removed from a body and the expansion and performance of the round was impressive. I think it was 2 or 3 rounds to the chest region and man was DRT.
