Interesting... I didn't realize that the SBR version of the PS-90 was going to be available directly from FN - It had looked like you'd have to do it yourself. The PS-90s with the long factory barrel look a bit silly, IMHO, but with the shorter barrel it regains the high degree of coolness of the military original, and will be worth waiting for. Now if they can issue it in black, and get the price of the ammo down, we'll be able to play Stargate SG-1...
IMHO, some of the coolest guns out there (legally) are the semi-auto versions of WW2-era MGs and SMGs. 1919, MG34, MG42, BREN, ZB26, DP, etc. I'm also waiting for Military Gun Supply to perfect their semi-auto PPSh-41.
