Leaving pressure in CO2 guns
 

I've heard that leaving pressure in CO2 guns is damaging to the gun, as opposed to leaving pressure in a gas gun, which is advisable.

Can you please tell me if this is true?

And does this apply to revolvers as well, meaning that I need to remove the CO2 canister when the gun is not in use?

Thank you very much,

You can't really remove the CO2 canister because the first time you screw it into the magazine, you break the seal on the top. Removing it from the magazine will simply vent all the CO2 into the air, and you'll have to screw in a new canister. You'll have to just remove the magazine from the gun and keep it separately, with the CO2 capsule still inside the magazine. Its always a good idea to not leave the magazine in the gun, whether its propane or CO2.

So, are you saying you can leave the pressurized CO2 capsule in the magazine?

And what about revolvers, where the capsule is in the handle, do you need to take it out when you are done using the pistol?

Yep, leave it in the magazine.

I believe its the same with revolvers. You have to screw in the capsule at the beginning and that breaks the seal. So yes, leave it in there until its empty.

Don't take your cartridges out even if they are half full. Especially in GBBR magasines. By doing so, the cartridge will freeze, expand inside the magazine and will be hard as fuck to take out afterwards.

Freezing contracts metal, not expands.

My bad. Still the material inside the GBBR mag contracts onto the cartridge.

Great. Thanks for the help.

I always was told the opposite for co2 in air rifles, that when you are done remove the co2 cylinder regarless of what was left in it. The reasoning behind this as i was told is that the co2 will destroy the seals overtime being pressurized. I may be wrong but I always take the co2 out of the gun/mag/wherever it goes.

Same goes for me...shoot until co2 is empty then take the cylinder out...

This is an issue i'd like to see solved forever. Revolvers do not use mags, therefore the co2 cartridge is only screwed in and bam. The only way to take it out is to unscrew it and pull it out.

Someone needs to get on this and confirm if either leaving it in for extended periods of time ruins the seal
OR
confirm if taking it out freezes the seal, and makes it brittle, prone to damage, etc...
Or both of those.

OK, now I am confused again...

Basically, leave the CO2 cartridge in the Magazine, and simply remove the magazine.

I've got a gun that's had a CO2 capsule in it since mid-late October. I test fired it a moment ago and it's still got CO2 in it. I imagine that it'd be empty by now if the seals had been damaged.

I have an ASG Duty 1 CO2 pistol (the CO goes in the handle of the gun) i leave it in the gun when not using it.. I can't see it hurting the gun as it keeps pressure on the seals so they don't dry out. Just take it out once in a while.. i do it every week and fire it off in the backyard. (i also have 2500 crappy bbs that don't feed in my AEG that i use to fire off in my pistol so i do it more to waste the BBs) I don't see it hurting it as it is designed to take the pressure.
