on my pump gun I just recieved I have an none on off asa, when i screw the bottle in its real easy just screws right in but when I try to get it out thats another matter its only possible by putting it between my legs and twisting to get it out, is this because it is a none on off asa as with my etek it's easy to get out once i've un aired it but I dont see how i can release the pressure from this as if the asa is the problem then am just gonna save for a decent asa. thanks for any help
