I'm in a similar situation - my first gun is a shotgun, and I have yet to shoot it. I've been trying to find a "shotgun basics class" or something similar but haven't found any.
I have a 20 ga. I don't think they make 00 or 000 for it. I wonder if they would allow #3?
I was looking at something similar to that KZ Universal Shotgun Magazine Tube Mount that was twice as much! (INSIGHT CFL-900-A1 - Shotgun Mag Tube Rail Adapter INSIGHT CFL-900-A1 - Shotgun Mag Tube Rail Adapter...
No one included beer?!? :shocked4:
Hmmm, maybe I should put one of these together. Offhand I would put in it:
Gauze and medical tape (to make band aids)
Quick Clot (for big boo boos)
folding knife
Among other things that have been previously listed here.
