Dan Wesson made, in my humble opinion, some of the finest revolvers ever made. I've owned a couple of them in 22, which is built on the same frame as the .38/.357s. Still own one. Great shooting guns. About the only thing I can say "bad" about them is they are BIG, HEAVY guns, especially in 22. They're actually about the size of an "L" frame Smith and Wesson. Also the sights on the adjustable sight models need an Allen Wrench to adjust them. Not a real problem as long as you have the/a set of Allen Wrenches with you.
Dan Wesson's have interchangable barrels, that you can change out with just a wrench and a go/no go gague. (Automotive feeler gagues will work fine.) Their grips are also interchangable. They're one piece and can be shapped just about any way you want them. Some DW's came with an extra block of wood to "carve your own."
I paid $350.00 for my current one last year, they were asking $400.00. The same dealer has a couple of .357's now and they're asking about the same for them IIRC, so $450 might be a little high, or not, depending on the area, condition, barrel lenght, etc..
The "Monson, Mass guns are generally considered to be the best of them.
