Walther CPS carbon dioxide Air Pistol.
177 calibre pellet pistol; 8-shot per holder
Looks identical to this -- just taken with a better camera.
See the following pictures to see what it comes with. Three "aftermarket" pellet round holder thingies, one "Walther" one that came with the gun. The smaller case of BB's are for sissys... (lol -- just a joke) -- these are the rounded off pellets. The ones in the plastic case are more pointy, and (I think) are much more accurate, but that's me. Gun works great. Never really used it, just kind of a thing to play with every so often. Does not come with Co2, however, you can buy them at Canadian Tire or where ever.
Looking for $100 OBO.
