Crosman introduced the Crosman C51, their latest Blowback CO2 BB pistol in 4.5mm - .177 caliber. It looks a lot like a Glock or perhaps the Umarex SA177, nevertheless it looks like a nice gun!
I don't have too much on it just yet for specifications other than it takes up to 20 - 4.5mm steel BB's, uses a standard 12 gram CO2 cartridge, and of course is a blowback operated gun with a metal slide and polymer frame.
I'll let you know more when I know more...
