I think the guys I'm playing with have roughly the same idea -- they want some pistol only games. I was already looking at a Beretta M9 duplicate, so I'll look out for the brands you listed. Ironically I might get the pistol first, since currently pistols are all we've got. I'll need to make a trip down to Victoria or across to Vancouver in order to get age verified, though. I'm currently stuck in Nanaimo, sadly.
Another question: are all pistols gas operated, or are there electric pistols?
