survivalnut Ron seems to have a sorry view of a great revolver when in the hands of the wesson family. The pistol packs do draw a premium fee of up to a 1000 dollars and can be worth it to a collector. Many DW revolvers even with many years of use still will look good and out shoot anything S&W has even today from the custom shop. Sights work very well with many options and triggers have a shorter pull and faster hammer drop than others.
Heres one for a what looks to be a deal- http://www.gunsamerica.com/941906444/Guns/Pistols/Dan-Wesson-Pistols-Revolvers/Revolvers/Dan_Wesson_357_Pistol_Pack.htm
S&W revolvers never were the handgun of choice of silhouette shooters. Dan Wesson or Freedom Arms for revolvers are the brand to own or atleast to win with .
The DW you want to look for first would be from the MONSON.MASS or early PALMER area, after that the Wesson family members were not involved.
The single revolvers can be found for 400 dollars + or - 50 bucks in 90 to 95% condition for a quality shooter.
There are some guys over at danwessonforum that also make barrels and shrouds, sights and many small parts- EWKarms along with CZ for maintaining them .
I have 4 of them .22lr, 2-357mags -15-2 series and a 44mag all monson mass revolvers. Bought my first one in 1976. Never had a issue with any.
BLUE RIDGE BLUEING use to do DW handguns and is still is a favored bluer to fix any flaws if needed like on this pistol pack above.
Just run some searchs for DW pistol packs anf visit the danwessonforum to see what turns up.
