I do a lot of pistol dry firing indoors with a laser cartridge during the winter months. I have been looking at some Co2 pistols as something a little less boring than dry firing. The Crosman Custom Shop can build me 2300KT CO2 Carbine for under $300.00. For the price it seems to have more features than any other Co2 I have looked at. I would prefer Co2 and not PCP or spring operated pistols. Any suggestions for something in this price range would be appreciated.
