PDWs...and other small arms.

[JASmith]

I think that the reference to 50m might have been in the context of a stocked PDW like the B&T MP9 (which has recently been developed in .45 calibre).

You're right, I had neglected the Tommy Gun!

That one had a lot of advanges -- shoulder fired, good sight radius, and a barrel length that gave the .45 a solid velocity boost. It would indeed do well at 50 meters.

{Don't even want to start talking about the M-1 carbine...}

Also, I am having a hard time adjusting to the notion that the PDW is primarily an ultra-compact carbine that can, in an emergency, be used as a classic pistol. This change in use pattern will also impact preferred sight systems and cartridge optimization.
