cp99 compact air pistol schematics

[almoreno95111]

Hi I just purchased my co2 powered walther cp99 compact airgun
Sweet pistol. Im just a power fenatic and I was wondering how I could make this pistol get more f.p.s. I wanted the scematics to the pistol so when I break it down, I will know how to assemble it back together again.

A google image search will give you plenty of results. In order to increase power, think of ways of fitting a longer barrel, increasing hammer spring strength, hammer weight and valve flow.

Thanks for the suggestions Jackssmirkingrevenge. I have recently made an attachable silencer looking ( not an actual silencer) extended barrel, but have not been able to properly test, due to weather issues. Would like to furfher dissasemble pistol to look at hammer weight opptions and chek valve. But I will not do that till I have the scematics. Well thanks again. Will post my findings on the extended barrel testing in a few days.

If its the .177 CP99 Compact and not the Airsoft model then I have the Schematics in an Email I was sent. PM Me and I can Email them to you.

My gun never worked right,the power was laughable and I tried 2 new valves in it and still no good.I paid a fortune for it as I'm in Australia where they are illegal and it just refused to shoot correctly!?. Worst money I ever spent.


I have many pics of the internals,its a really,really fiddly gun to take apart and re- assemble , not nice to work on. After taking mine apart sooooo many times I can do it reasonably easily now
