Recently, a local pawn shop had an Interarms Virginian Dragoon sit in the display case for well over a year, at $500. I've seen plenty others at bargain prices, but I never overcame my reticence, based on some details that bothered me.
Do some research and you'll find out the history of these revolvers is, to put it politely, mixed.
There's an excellent, well researched article posted online by Lee Martin, who is over on a single action forum. It's easy to find with a little search.
Anyhow, production started chaotically, with lots of quality control problems. If you're into accuracy and if you're a hand-loader, you might be disappointed. Bores, throats and chambers are all over the map, dimensionally, and often exhibit sketchy machine work. If you're into single actions from a cowboy standpoint, the Virginian Dragoon is just enough off from a Colt SAA to look kinda goofy, in my opinion.
The high point came when interest in the revolver coincided with the Metallic Silhouette boom in the early 1980s.
The one I saw locally was one of the 1980s long-barrel silhouette models. It appeared to be one of the good ones. As Lee Martin points out, these have a long free bore, much like what is now referred to as "Taylor Throating".
If it were any of the others, including the bicentennial model, I wouldn't bother.
