Walther CP88 Competion leaking…

[MrNick54]

Hi,
I would be grateful to receive any recommendations for repair/servicing providers for my CP88 Comp, which appears to have developed a defective seal causing CO2 to leak when loading a new cartridge… presumably the piercing seal needs replacement?
I’ve looked at a couple of Youtube videos but think this is a bit beyond my capability!!!
Many thanks in advance.

Having owned 2 CP88s in the distant past and just broken down for servicing a Umarex 1911 A1, the main problem is the number of small springs and pins which love to fall out. I would advise taking your time, taking pictures and disassembling over a towel to trap anything that does decide to make a break for freedom.

It depends where the CO2 is leaking from, out the barrel could be seal in the valve block or in the handle could be a compressed piercing seal. The valve block if I remember correctly literally lifts out once cases are split so pretty simple. You'll need a valve tool which are cheap on ebay ur make your own from a big flat head screw driver.
