Perhaps I'm just missing it.

I don't get it. In simple terms it's a 45acp but using modern powder they can make it with a shorter cartridge. I understand that.


Please explain how a shorter length cartridge translates into a more compact pistol. It's shorter, not skinnier. Is the 45 gap pistol skinnier than a G36? I don't think so. Is the slide narrower than a G36? I don't think so. A G36 is a .45acp pistol and it's darnded skinny.

If they wanted to Glock could just make a larger G36 and who knows it might be a smaller pistol than a G37. So what advantage is a shorter length .45acp cartridge?

Inquiring minds want to know.

How many times do I have to say this.....

The GAP was designed for countries that forbid civilians from owning firearms in military calibers. I have friends in Europe that are really excited about the GAP because now they can finally own a .45 pistol. Goes along the same lines as the Glock 17s in 9x21.

While I will not say I know anything about the previous post, you can get .45 gap into a smaller frame then .45 acp.  It does not change the width of the grip.(which would relate to the bullet diameter)  But it can change the front to back measurement of the grip frame.(From the shorter cartridge)  The GAP is built on the smaller glock frame. (Same as the model 17/22)  It does not use the larger grip frame(10mm/45acp).   If you look at one up close(I saw one at the GSSF shoot in NH)  The frame is the 17/22 but the slide is the size of the 10mm/45.  Then they tapered the bottom edge of the slide so it bevels down to the slide to smoot it out.  Also the use a thicker based brass to help with the fact that the case is not supported at the 6 o'clock area.(Like all other glock barrels)  This basically stops or minimizes case expansion due to this fact.

I shot 5 rounds through it and it felt nice, with typical glock accuracy.  Recoil didn't seem any different then the 45 acp.  It was a bit loud as we were under cover while shooting though

Also one of the gun rags this month compared rounds from manufactures using the same bullet weight etc and the GAP had more muzzle velocity and enrgy then the 45 acp, due to the increased preasure due to the smaller case.

Hope this helps......

Never heard that... And I have had extensive talks with folks about the new cartridge.

But...

Isn't a G36 Glock .45acp the skinniest pistol Glock makes? Why isn't the G37 skinnier?

ps I think the foreign use of 45 gap probably is a good explanation. Don't know why they are pushing it in America.

The G36 Width is 1.13 in (28.5 mm.)

The G37 should be Width 1.18 in.(30 mm)


so yes the G36 is thinner, but barely.  I think alot of it boils down to it being easier to design a slide to fit the 17's frame since the had federal (?) i think's input on the ammunitions design and it killed several birds with one stone(i.e. countries that don't allow military caliber weapons), I think it was a wise decision on their part






here is the comparision between a 37 and 21

                       Glock 21 .45 ACP   Glock 37 .45 GAP
Magazine Thickness 1.15 inch           0.904 inch
Grip Circumference 7.75 inches           7.375 inches
Grip Thickness           1.292 inches    1.182 inches
Grip Front to Back  2.155 inches     2.08 inches
Trigger Reach           2.938 inches    2.793 inches
Barrel Length            4.605 inches     4.59 inches

Quoted: Grip Circumference 7.75 inches           7.375 inches

This makes for a HUGE difference in the feel of a pistol.

Only advantage I see is for people in countries that aren't allowed to own .45ACP.  I think if you can't handle a G21 or G30 (because of the bigger grip) then you should use a G31 or G32 (.357SIG) but thats just my opinion YMMV.  LE circles seem to like the .357SIG.

I don't doubt the fact that Glock wanted a cartridge with his name on it. The fact that European shooters can now have a cartridge with .45 ACP punch is what makes it marketable.

We just need to stop thinking that Glock came up with this cartridge to replace the ACP.

And in my little world the Glock has replaced the 1911.

The G37 farme is the sme size as the G17/22, where as the G21 grip is quite a bit bigger.  Anyway that is what i was told.

.45 ACPish performance (supposedly), in a gun with a frame the size of a 9mm.  Nothing more than that.

The existance of benefits (or lack of benefits) to the american shooter will vary from person to peroson...

I dont think the GAP is any threat to the ACP as far as replacing it as america's favorite caliber,  and only time will tell when it comes to this cartridges effectiveness in live shootings.  I think it will perform as a whole about the same as the ACP, but it will take YEARS of actual shootings to have enough statistics to come up with a relative average.  

I for one would have some trouble with a G21 due to grip size... thus the GAP may provide another choice... but at over six feet and two hundred pounds I am more than well enough equipped to handle the recoil, so its not handeling the recoil as an ealier post said... its getting my fingers around the damn thing.

Ill stick with my G20 in 10mm, thanks very much!

Great gun... just a bit expensive on ammo

Same as .380 vs 9mm

It allows smaller-frame single-stack guns...

Still, a double-stack .45 is going to be one large weapon...

Why would anyone settle for less?  

Yeah but........


If they can make the slimline G36 .45acp then they can make slimline .45acp in the G37 size. The .45gap is not a "slimmer" cartridge.
