My Dan Wesson was made by High Standard! And has High Standard roll marks.
The Backstory: When Wesson was just starting out he made a deal with HS for them to make his guns. He got his product without having to invest in all the tooling, people, etc. The price: his name wasn't ON the gun. The High Standard .357 Sentinel Mark II and III were what they were called. His design (well, not exactly his, he got it from someone else) and his specs, High Standard produced.
I was "shopping" at my LGS and saw this 357 in the case with a nominally low price (about $425), took a pic, went home and did a bit of research, and rushed right back and bought it. I think they didn't understand what they had (figuring it was "just" a High Standard) and priced it accordingly.
It's a quality gun, great trigger in both DA and SA, and it gets shot occasionally (I also have a 66-2 stainless and a 28-2 and if I'm shooting in magnum, it's usually the 28 that gets used even though the 66 has a slightly better DA trigger.)
I look every once in a while for another, but I don't think I'll find a "deal" like this one. For my budget, the Wessons are a bit spendy.
