my new 2240 is not holding c02.
i have only shot one or two bulbs through it. fresh co2 will only have a few shots left in it, if left over night.
and i don't hear any hissing.
did not submerge the muzzle in water to check either

or am i asking to much to expect co2 in there, the morning after???
maybe i am not tightening the co2 cap down enough???

i don't really want to take it all apart but...i guess i will if i have to but....would rather not.

Expecting it to hold gas is not expecting too much IMO.

If it's new, is returning it an option?

If you can't return it, then it's fix it, live with it, park it or sell it.

I would choose to fix it. :wink:

Find the where the leak is coming from before you start tightening the cap more...no point in possibly making things worse. When you've found the leak, help can be provided if desired.

well imo there is only a few possibilities for where a 2240 can leak overnight...

1- co2 cap not holding the co2 tight enough to the valve seal (not overtightened, just hand tight no tools!!)
2- the valve stem, test to see if there is co2 comming out the barrel (muzzle) (observing safety rules)
3- if both of those are good then you got me!! i dont know.

Hmm, mine seems to hold CO2 for several days, although I'm suspicious that I do lose a few shots.

Maybe it will bed in a bit after a few more cylinders. I always give the top of a new cartridge a good clean and a drop of oil before putting it in the gun. I'd be cautious about trying to over tighten it as I suspect it is fairly easy to rip up the seal that way.

This step you have done, before placing the CO2 bulb into the pistol, Place some pelgunoil(Lub) on the nose of the CO2 bulb.
This sometimes softens the front valve seal and get a better seal.
May be try a different box of CO2.
If there is no sound of leaking, may be it is a bad front valve seal.
So if all is still lost, time to remove the Valve and take it apart and inspect.
Brand new pistol, usually if reported to the seller may be, they will negotiate some compensation or replacement.
But the 2240 should hold pressure for a very long time.

thanks for all you help guys but i think it was my fault.
i put in a new bulb, tightened it with a screwdriver.
i have left it for 24 hours and it's has lots of c02 left.
i must not have been tightening enough, or at least that would be the seal to look at first.

ps- returning it would not be possible as i put a steel breech on it and a 10" barrel.

thanks for your help.

I advise not using tools to tighten the cap, repeated overtightening can damage the seal. but if that was your problem and the "ONLY" way to fix it is using a screwdriver i would say the seal isnt doing so good.

just using your hand strength should be enough......
