Problem is finding them in Canada.
US? No problemo, Canada? Good luck. Importing is expensive.
My buddy just imported the +6 Breily (Supernova, settle down guys), and it was 185$.
Lawry Shooting Sports in Ontario.
THAT being said, I have a 1301 as well and would be interested. I was thinking of getting a +6 to run on my Supernova AND put a plug in it to run on the 1301. One extension, two guns... (I haven't exactly measured it out yet to see if it works...)
I know it would take some pre-inspection at every comp I went to though... Everybody would be saying I'm running a prohibited gun...
