Rich007 did you clarify that with PNHQ? I fully understand that a shotgun wiht a fixed mag exceeding 5 rds is P only, but is there any legislation for a firearms wiht a detachable magazine, which is A cat with 10rd, but P cat with more than 10? I have not seen this answered in the legislation but could have missed something.
I got this from the Firearms Safety Authority. I didn't ask about firearms with detachable magazines, but don't think it would be any different. The point was that I couldn't take the magazine extension off and use it for duckshooting as it would be a P endorsement firearm
