The manual for mine says take it out.
The manual for mine says take it out.
But that may be a safety suggestion?
I think I agree with Harvey S.
The only manual that I have seen that says leave it in is my SW 78g.
A gun that I have a lot of respect for.
I have a SMK CP1-M - the manual is very clear that you should never leave the CO2 capsule in for any length of time and tells you how to discharge a partially used one.
The consensus from some very experienced club members is that the neck end of the capsule will flatten the seal which will eventually fail to re-seal. A drop of gun oil on each capsule can help keep that seal pliable.
Like everything else we all have our own ideas and practices, go along with what you feel most comfortable with, good luck and enjoy.

I forgot to take one out of my 2240 once, it froze on there, was a nightmare to get off. Never again.

I have a Benjamin rifle which refuses to let an empty capsule go.
I have to attach a long car magnet rod ,cock and fire and then it comes out.
If the capsules are empty I take them out.
If partially full I leave them in - often for months at a time and have never had a problem.
I am not making a recommendation but merely stating my experience.
