PDWs...and other small arms.

[stanc]

.45 ACP is a NO-GO as far as PDW cartridges are concerned, and not really much of a viable cartridge for standard military sidearms anymore. One of the key parameters of a PDW is firepower, and being able to pack as much firepower in a lightweight and low-profile package. Once you start to carry .45 ACP in large quantities, you realize quickly that it fails horribly in this regard. .45 ACP is nowhere near a 200m cartridge...try 50m.

I concur with all but the last sentence. A .45 PDW ought to be capable of hitting a man at much longer than 50 meters distance. Some friends of mine and I one day were plinking at rocks on a hillside about 400 yards away, with a .45-cal Reising SMG. Shooting semi-auto, it was fairly easy to kick up dust within a foot or two of the rocks, and that with the simple open sights.
