Jeff Cooper helped invent the 10mm in 1983 for the BrenTen Pistol.

http://en.wikipedia.org/wiki/10mm_Auto for history

It was thought to be the ultimate in a self defense / hunting pistol cartridge.

I have owned 3 Colt Delta Elites...it is a handful, but performs very well.
I have taken antelope at 100 yards with it. One shot and dead !

Ammo is available but expensive. PROLOAD made the first US ammo for it that matched or exceeded the Norma load. Their 180 Gold Dot was superb and accurate. Unfortunately they are gone.

ANY 1911 firing it must have the proper recoil spring or you will crack frames.
The Glock 20 is very shootable !
