I am a Canadian and can only buy a PPQ 9mm with a barrel length of 4.17 inches or longer for it to be legal in Canada. The PPQ Navy 9mm qualifies since it has a 4.6 inches barrel, but I would like to have the Threaded portion of the barrel removed. (suppressors are not permitted in Canada and I have no use for it) My question is: How much barrel length will remain if I remove the threaded portion? Is there at least 4.17 inches or 106 mm left? Can someone please measure your barrel for me? Your help is really appreciated. I've been trying to get this info for some time now.
