Mine aren't airsoft, but BB. Made by Uramex, they look and feel a lot like the real thing.
Model 29, with the 8 3/8" barrel.
Model 29, with a 3 1/2" barrel.
I actually think of them both as more of a 27 myself due to the size of the holes in the barrels and cylinders. You load the CO2 cartridge into the grip, the load the BB's into brass "cartridges." From there they load and shoot like the real thing, just with a lot less expense, noise, and recoil.
Just to show off a couple more, I've got a 5" Schofield...
And just for real grins and giggles, an M&P semi.
Any real use for them? Not really. I ordered them over the Covid period, when I couldn't get out like I normally did, so I was bored. I knew they were guns I'd never actually lay out money for, so I sort of thought of it as building a "gun collection" on the cheap.
Might as well show this one too...althought I'm sure most people have seen it.
Thompson sub-machine gun...CO2/BB. This was the first one I got, and it was so much fun, I got started down the slippery slope.
I don't shoot them a lot, but they are fun. They'll roll a can around pretty good.
Edited to add: Note, with the exception of the Schofield, and the Thompson (of course) these are all licensed by Smith and Wesson.
