Well, you did ask.
I've wanted one of them for years, but just not bad enough to actually spend the money for one. Still, I liked the look and the feel.
Then a couple of years ago, during the Covid shutdown, I found one I was willing to spring for. It came from Pyramyd Air, and shoots BB pellets and CO2 cartridges. I was bored when I ordered it, and it helped that it could be shipped right to me at home. The CO2 cartridge goes under the grips, the BB's load into a brass cartridge. The gun works just like the real thing. Opening the action slowly lifts the "spent" cartridges. A good snap, will eject them.
Made by Barra it's all metal (of some kind) except for the stocks. Weight is about 2 pounds. The trigger is surprisingly good. I've never actually fired it though, having bought it simply as a "prop"; a gun I'd like to have but knew I'd never actually buy.
They're also available with a 7" barrel, and with a "nickel" finish. Sort of fun for a 100-130.00 depending on barrel length and finish. If I still lived "up nawth" out in the country, it would be one of my "bumming around guns."
