Haven’t notice anyone talking about this, so I thought I will bring it up.
if it is possible, when purchasing co2 cartrige make sure you always purchase the same make/model or what ever you would call it.
Reason being the top/tip are shaped differently between make/manufacturer, so if you use one type for a while then later change to another, it could cause leak due to the rubber seal being pressed into the shape of the previous cartrige tip.
I don’t think i’ve ever pulled apart and co2 mag to change the seals, so I am no sure how easy they would be to replace, so yah…
Also always keep that seal, or any seal for that matter in the pistol lubricated/oiled, this will help protect them from getting dry up by the gas.
