Double-Action 357 Magnums: Ruger & S&W Revolvers Tested

Among the most popular revolvers is the double-action 357 Magnum, and shooters can confirm this because Smith & Wesson recently reintroduced the Combat Magnum and Ruger has introduced a seven-shot GP100 357 Magnum. Those companies wouldn’t (purposefully) add a couple of dogs to their inventories. Shooters like the 4-inch 357 configuration because these revolvers make for excellent all-round hunting, personal defense, and target guns. Some revolver fans also favor them for concealed carry. Also, they will stand up to long-term storage and come up shooting. It is interesting that a number of special teams in Europe and the U.S. Military keep the 357 Magnum in inventory for this reason.

Readers have asked us to revisit the category with an eye toward picking a used wheelgun that could save them a couple hundred bucks — that is, they wanted us to go bargain hunting. So we purchased a quartet of used revolvers from major brands that included adjustable sights with 4-inch barrels capable of serving for some types of hunting and for home and auto defense. In other words, we wanted the best go-anywhere do-anything revolver, not a specialized concealed-carry type, such as the Ruger SP101. The 357 Magnum is a great defense cartridge and also a fine pest and varmint round in accurate handguns. With the proper loads, the cartridge is versatile and will take deer-sized game at modest distances. Also, a major advantage of the 357 Magnum is the ability of the revolver to chamber 38 Special +P or stouter cartridges, but as important, softer-shooting loads as well. A practice regimen of twenty 38 Specials for every Magnum is recommended by most trainers. We elected to test the revolvers with both 38 Special and 357 Magnum loads and also to include handloads that have proven themselves. Interestingly, the two Ruger GP100 revolvers, one in stainless steel and one in blued finish, showed practically the same firing line and absolute accuracy performance. However, the two Smith & Wesson revolvers, also one blued and one stainless, had considerably different characteristics.

The test firearms started with the Smith & Wesson Model 19 Combat Magnum, $800 used. This particular Combat Magnum came with a display case and a knife with matching serial number — pretty neat, but also pricey. The Combat Magnum name gave way to the Model 19 designation in 1957, the year when Smith & Wesson changed from names to model numbers. It has always sold well with a 4-inch barrel, in either bright blue or nickel finishes. Other barrel lengths have appeared as well, with 6-inch (1963) and 2.5-inch (1966) barrels showing up as mainline production guns. There is also a rare variation of the Model 19 with a 3-inch barrel. The Model 19 was dropped from the line in 1999 as police agencies migrated to semi-autos, but Smith & Wesson reintroduced the Model 19 Classic (4.25-inch barrel) at the 2018 NRA Annual Meetings & Exhibits (Model No. 12040, MSRP $826). There’s also a Performance Center Model 19 Carry Comp No. 12039 (MSRP $1092) with a tritium front night sight, custom wood and synthetic boot grips, and a 3-inch PowerPort vented barrel for recoil management. The revolver features a trigger overtravel stop and Performance Center tuned action. We previously tested a less-expensive Model 19-4 nickel-finish variant in the March 2015 issue, giving it an A grade.

Next up was a silver-skinned copy of Model 19, the stainless-steel Smith & Wesson Model 66 Combat Magnum 38 Special +P/357 Magnum, $420. In July 1971 Smith & Wesson announced its first stainless-steel 357 Magnum, the Model 66. Like the blued Model 19, the Model 66 was a favorite of everyday cops who wanted a Model 19 that was rust resistant. The 4-inch-version, like the one we tested, was the most popular. It stayed in continuous production until 2005, when Smith & Wesson dropped the Model 66 at its 66-7 iteration. Then production on the handgun was restarted in 2014, with the 66-8 unit, which is still in the catalog as Model No. 162662, with a suggested retail of $849. In the June 2001 issue, we tested a 2.5-inch-barrel M66, saying of it: “Even with the small problems we encountered, this is a superior weapon, and few revolvers can match this incarnation of the snubnosed K-frame.” In the April 2002 issue, we tested a 4-inch Smith & Wesson M66-2, $219. That Smith & Wesson Model 66 was gauged to be in 95 percent condition, which would bring a Blue Book price of $300 at the time. It earned a “Buy It” recommendation.
