noise when i remove co2 tank

when i remove my co2 tank it goes 'psst'
is this normal

yep is because the pin from the guns asa is still pressing on the valve of the bottle whilst it unscrews until you get to the point where the pin no longer pushes the valve and the carbon dioxide stops comming out, the psst noise is just the CO2 comming out before the valve closes its nothing to worry about.
