Way back yesterday, when I stopped at Gander Mountain, every new and used double and O/U in the place had a single trigger.
If there was an above described gun in the store with barrels longer than 28", I didn't see it. I don't think I saw a 28, to be honest, but, my eyes glazed over after about the third used Browning Citori with a glossy finish on the stock. I can only take so much of that before my eyes glaze over, and I start thinking about how much dog poop is in the yard, and how I should do something about it, instead of standing here with glazed over eyes. 26" barrels were still common, however.
Mostly autos and pumps, but, I didn't pay much attention to them.
What sells at the big retailers seems to have little correlation to what people here seem to be interested in.
The more things change, the more they stay the same, Larry.
Best,
Ted
