Good day all. I have recently bought a 930 JM PRO. This is my first semi auto Shotgun. I am in Canada so my 930 does not have a mag tube extension. Is it necessary to remove the mag tube spring for regular maintenance? I can remove the cap for disassembly and there is still a retaining clip to hold the spring in place. I can't see there being a problem but I would rather be safe than sorry. Thanks for the assistance.
