There have been rumors about a Glock carbine for decades. Over the years, people “in the know” have claimed to have seen a prototype. My
guess (no, I have no inside info) is that they tested a prototype years ago, and simply decided that while it was a neat little product, for
them, it wouldn’t be profitable. For example (and these are only examples), maybe the molding equipment they own isn’t large enough to mold frames for a carbine, or their rifling tooling isn’t setup for longer barrels, and the massive cost of retooling for one product just doesn’t make sense.
As cool and fun as pistol caliber carbines are, and yes I own one myself, how many do they really sell? Marlin, Beretta, KelTec, Ruger, Vector, Kriss and others have tried it, and most have given up because pistol caliber carbines just don’t sell in volume. If you make a sub machinegun or SBR, everyone wants one, but the market of people who can or will go to the trouble to actually own one, is very small. If you make an inexpensive carbine (same cost as a pistol), no one is happy with the performance. If you make a carbine on par with the performance of a military carbine then the price is too high. Or you could manufacture an inexpensive carbine with sub-par performance and price it like a military carbine (not mentioning any names
).
Try as they have, police departments just don’t seem interested in issuing companion carbines with the officer’s pistols. You can make all sorts of great arguments for it, but it just doesn’t seem to drive sales. Don’t know why, but it simply doesn’t.
Any one care to guess who I'm referring to with the "sub-par performance and price it like a military carbine"?
