I used to carry an 18” Winchester Defender in a cab top carrier in my F-250. The shotgun fit fairly tightly between the cloth covered carrier and the roof. Two velcro strips kept it secure. They also kept the gun from contact with the metal.
Almost no one ever noticed it. For some reason people just don’t look that way.
My Winchester Model 1300 Defender (pistol grip) has an 18 inch barrel and an overall length to the back of the grip of 28 inches...Had it since the mid-90’s...Dbl 0 or flechettes are my choices...
“18” Winchester Defender”
Nice piece among some practical 3-4 shotguns. Not sure what’s the preferred sequence, a round going off followed by racking another or vice-verse. Me, myself, personally leans to well oiled mechanical sounds....snick-snick.
