I always hear that I build my guns in weird calibers.
Figured I would do this one in another weird caliber... .45acp
For those that have never heard of .45acp, it is a really old caliber invented in 1905 by a guy named John Browning (he was kinda a gunsmith fella years ago).
.45acp has been used in many platforms since then, including 1911s (a handgun), Glock 21s (also a handgun), Thompson's... and well... lots of other guns also. IIRC, Hi-Point even builds a .45acp. So, the caliber covers the spectrum from gangsters to Wilson Combat snobs.
This particular carbine shoots well with Glock 21 mags (normal and high capacity). Bullets speeds vary from 1,100 FPS to 1,850 FPS... the later being a very hot .460 Rowland load.
It is hearing safe with a Lane .458 Magnum Scorpion can. It is also reasonably accurate out to 200 yards. Recoil is virtually nil.
