Glocks Different Design: .380 ACP Pistols:

 - Glock were estimated in 2007 to have sold more than 5,000,000 guns since Austrian production commenced in 1982. They must surely have made more than 6 Million by now - but I have never heard of them releasing any production figures.

If Glock were to develop and market their own model in .22" L.R. Rim-fire for sale in USA & the rest of the world - I'd bet the farm that they'd sell a million of them real quick. - Just look at the excitement caused by the recent announcement by Ruger of their new Mark IV .22" model:

Glock do make three guns in .380 ACP caliber - but there is only one of them generally available in USA - and that is the Model 42 - said to actually be made by Glock in Smyrna, Georgia.
Glock 42 .380 ACP - Made in America.
Only ONE Locking Block Pin Needed

The Glock 42 is a compact pistol with a single stacker 6 round magazine and a 3.25 inch barrel - and it is 'all Glock' in that it uses the locked breech operating system.. A small soft shooting pistol that is perhaps better suited to folks with smaller hands.

The other two .380 ACP guns - the Glock 25 and the 28 - are 'blow-back guns' and are not generally imported into 'Murica' because their method of construction loses them BATF points under the 1968 Federal  GUN CONTROL ACT - so they are only available as Official Law Enforcement sales there.
Glock 25 is same Size as G19 9mm.

These .380 ACPs are made mainly for sale in countries that restrict ownership of "Military Calibers" - but the technical feature here is that the .380 ACP cartridge is sufficiently low powered that it doesn't need a locked breech and will happily function by pushing the slide back against the inertia of a recoil spring and an unlocked slides' mass. Indeed when used in a locked breech - the mechanism needs to be adjusted to function at the low chamber pressure.

This low pressure / low power ammunition results in LOW perceived recoil too.
Glock 28 .380 ACP - same size as G27 & G26.

Now these two Glock 380 ACP blow-back guns do not use a fixed barrel like many other small caliber blow-back pistols do - but their barrels drop at the breech end when the slide opens - they are just not locked in place when in battery.
I really wanted to show the difference in the mechanical detail - but I can't honestly say that I see it.

-There you go then,
