I call them combat handguns, but it's the same thing. Pretty much any quality, full-size pistol in 9mm-.45ACP (plus a few other calibers I won't go into) that is tough and durable enough to last through a dusty, dirty battle and reliable enough to not fail during said battle.
How many 1911s fall into that category though, I dunno...
ETA: Please note that the above is my definition, not necessarily the RIGHT definition
