Air gun replica's are the only kind I'm interested in. I don't shoot them as much as I sort of "collect" them. They're replica's of guns I've never owned and probably never will, but I have a couple that are of favorite guns.
It got started with a Uramax Colt SAA. I have fired this one a few times, but it's mostly just a "toy."
Then I heard about this one. It was a MUST have. I've had a lust for a Thompson Submachine gun since watching "Combat" as a kid. This is about as close as I'll ever come to having one.
Uramax Thompson M1A1 (Kimber Micro 9 for size comparison)
Once I had the Thompson, I HAD to have a 1911 to go along with it, so I got this one, a "John Wayne" commerative.
One of my favorite "I'll never buy one" gun is the Smith and Wesson Schofield revolver. But I can buy an air gun replica.
And last but not least, even though I don't care for a long barrel revolver, I went ahead and bought a Smith and Wesson Model 29 "Dirty Harry" gun. If they ever bring out one with a 4" barrel, I'll have another one.
They all function more or less like the originals. The cylinders open, you load with a cartridge. The Thompson fires both full auto and single shot. Air cylinders fit into the butt or the magazine area. Trigger pulls are much better than you'd expect for such inexpensive guns. I've got less invested in my "collection" than I do in some individual firearms. I just think they're "COOL."
Oh, I've got a M&P 9mm on the way this morning.
