My first revolver was a model 715 (stainless) 8" barrelled .357. Well made and very accurate. The interchangeable barrel system is good and contributes to its renowned accuracy. It's been described as having the barrel in traction. Eliminates barrel flex. DW revolvers are also very strong and lock up at the front of the crane as well as the back of the cylinder.
Some time ago, DW Arms changed hands and became Wesson Arms. At this point, I purchased a fixed 5" model 15. It's still very accurate but fit/finish wasn't up to the first ones (1st. Gen).
I recently saw and handled the latest version of Dan Wesson Arms, now located in Norwich, NY. This thing is beautiful. Superb fit/finish and they use an etching method that looks awesome. Another forum member spoke to a DW rep who was very proud of this etching method. I was so taken with it, I ordered another one.
In short, they're big, brute strong revolvers with exceptional accuracy. But you want to stick with the 1st. or 3rd. generation models.
