for pcp or co2 pistol

[gfradI]

what is best, keep air or co2 cylinders filled and connected to pistols or cylinders disconnected from pistols during storage

[Rover]

I keep one on and one off. It doesn't seem to matter.

Greetings,

I have a Walther CP-3 (CO2) and the instructions say to keep a charged cylinder attached when not in use.

Cheers,

Dave

I’d recommend disconnecting the cylinders to avoid potential leaks or pressure damage over time—better for safety and longevity.

Most CO2's use a hammer to open the tank valve to discharge a shot.
To protect the valve surface keep the tank on the pistol but do not cock the pistol, less spring strain.
PCP pistols on the other hand have a pre charge chamber with a pressure reducing valve (spring operated),
to reduce spring pressure do not have the tank fully screwed on to the pistol.
Either use a tank spacer to screw the tank off the valve, leaving the tank on the pistol with the spacer installed
or remove the tank off the pistol and store seperate.
