Well, one thing that caught my eye was that the 10mm holds about 150-200fps more velocity at 100yrds than the .45acp does at the muzzle. I never intended on getting a 10mm but as of recently I came into a 2nd Gen Glock 20 and am right in love with it. 10mm Vs. .41 Mag?
Hmmmm.....ill take a G20 sir
All these "revolver-vs-auto" debates miss the point, in my view.
What people seem to forget in this and similar "10mm v. .41mag" dust-ups is that one of the original concepts for the 10mm AUTO (in reality, a lengthen .40G&A case that moved up from a 180gn-weight, 38-40 slug in the latter to a 200gn-weight TMJ bullet in 10mm, and in velocity from 1000fps to 1200fps), was to put "
magnum-level" power into an
autoloading envelope.
Magazine capacity was intended to be, roughly, about midway between the 7-shot .45 1911s and the 15-rd 9mms of the day (
circa early 1980s).
A 10- or 11-shot autoloader, firing real high-performance (i.e., magnum-level) 10mm ammo - along with its way faster reloading capability - has it all over any 6-shot revolver, regardless of caliber, for the purpose for which Cooper had conceived it: military use first and, later on, for law enforcement and civilian self-defense use.
That that purpose wasn't fulfilled by the Bren Ten itself isn't the fault of the cartridge.
Arguably, the Glock 20, or one of Smith's 10XX-series guns (like the 1006 or 1066), provides the better 10mm envelope to achieve the original uses for which the cartridge was created in the first place.
Old School.
