I recently noticed that the FHP has gone to another caliber, anyone know what happened to their supply of .45 GAP ammo?
I've been looking for a while for some.
Thanks

I asked at GT distributors if there was any 45gap ammo. They said they had very little and was offering it for those who bought one of the 45gap Glocks. Supposedly a lot of troopers bought their old duty weapons so the ammo was probably gifted to troopers.
 
Here's an off-the-wall question. Can .45 GAP ammo be used in moon clip fed revolvers like Model 25s and 625s? I can't find the dimensions of the shells compared to .45 ACP.
 
That is why I bought some of this. I also have some .45HP one of the guys gave me a heads up on here. It is a round that had a 1mm shorter case than .45acp. J&G had some a few years ago, for cheap. Less than components even in cheap times...........
 
Yes, the GAP will work in revolvers using moons.

Right, but it will not work in ACP revolvers without using moon clips. Both headspace on the front end of the case, and the GAP case is shorter than the ACP case, so it must have the moon clip to headspace on.
 
Folks have learned from past mistakes during ammo shortages that it's good to have at least one firearm chambered in an off-cartridge, so a lot of folks bought firearms chambered in things like 9x18 Makarov, .357 SIG, or .45 GAP as an alternative during ammo shortages.

Problem is, high profile YouTubers kept on suggesting that everyone do it, so now those alternative cartridges are all gone too.
 
This is just my own theory, but anyone who currently owns a 45GAP should stock up on ammo, components and magazines because I truly don't see a healthy future for the caliber.

Anyone who is considering buying one, would truly be much better off buying a 45 acp which will be here for a long long time. I see no advantage and lots of disadvantages with the GAP caliber. Just my opinion and YMMV.
 
The GAP is really a nice shooting round approximating 45 ACP ballistics in a 9mm size frame...easy to reload with 45 ACP components...it should have been more popular but like the 357 SIG, it has been eclipsed by “9mm Mania”.

I shoot 45gap in my 625-2. I know the drawbacks as far as carbon and powder build-up, etc. My question is this: From purely a ballistics standpoint, is 45gap safe to shoot in a model of 1950 (pre-26) and model of 1955 (pre-25). I know the pressure is a little higher in the 45gap vs.45acp. Not that it matters, but I only shoot standard velocity in these guns, no +P.

The caliber has been unhealthy for a long time. It's a fairly pointless caliber. Imo 357 sig is also pointless, but it does have its fans. I've never seen a 45 gap fan. For anyone that actually plans on doing any shooting its a bad proposition. During "normal" times trade in gap guns usually only seem to be about $50 cheaper than trade in 40s&w guns. After just a few box's of ammo you will have shot up that price difference.

That’s a hard one to know for sure. Most 45Gap does come across a little hotter than 45acp. However, with very similar 25s made from the same metal chambered in 45Colt I think it will be fine. Just think of some of the hotter 45colt loads shot through pre model 25s.

I believe Glock killed the 45gap success from the beginning by making the slide 1.125” thick instead of 1”. The prototypes had a 1” slide and even magazine writers were provided and wrote that the slide was 1” thick. Glock made the 36 with a 1” slide.

I have known one person that was a 45gap fan. He had also put more dirtbags in the grave than any cop I ever met. However, I don’t believe he ever shot anyone with anything other than 38 or 9mm.

Realistically speaking, this is not a valid concern. Ammo manufacturers continue to do limited production runs of cartridges which have long since fallen out of use such as 7.62 Mauser and even obscure cartridges which never achieved any sort of widespread use such as 9x18 Ultra/Police, so .45 GAP will most likely remain in production for decades to come.

FYI: Firearms chambered in .45 GAP are NOT 9mm size firearms in terms of overall dimensions, they tend to be significantly thicker in the slide, as you would imagine since you cannot very well mill out a slide designed to house a 9mm bullet to accommodate an 11.5mm bullet and be left with enough material for the firearm to be structurally sound.

Folks complain about how the Glock 22/23 Gen 5 have a thicker slide than previous generations eventhough they're really only a bit thicker and the thickness actually serves a purpose because after all these years Glock has finally gotten with the program and accepted that you cannot simply bore out a slide designed to house a 9mm bullet to accommodate a 10mm bullet and expect it to hold up well to regular use.
Yeah, you know all that stuff folks like James Yeager are always saying about .40 S&W tearing guns apart? That's what happens when firearms manufacturers lazily rechamber 9mm pistols for .40 S&W. It's also why Smith & Wesson's pistols tend to have overall thicker slides than other brands, because they design their firearms specifically for .40 S&W, then bore their .40cal slides out for 9mm.

Fortunately, Glock couldn't physically bore out a 9mm slide for .45 GAP, so they had no choice but to design a slide specifically for .45 GAP.

TL;DR -- If you line up a Glock 17 side-by-side with a Glock 37, you'll find that it is significantly thicker than the Glock 17. They are by no means identical in overall dimensions.

It's a very valid concern. If this cartridge is like others that aren't very popular, it may be years between production runs. As its minimal popularilty further decreases, even the limited production runs may be phased out. With companies like Starline that are very receptive to shooter's wants and needs, the situation could be different, but no guarantees.

Best to stock up on ammo and/or components when and if they become available.
