Smith & Wesson Model 686

The 686 has been available with 2.5, 3, 4, 5, 6, 7 and 8 inch barrel lengths as standard models and other barrel lengths either by special order from S&W's Performance Center custom shop, or acquired from or built by after-market gunsmiths. The Performance Center made a limited number of Model 686s chambered for .38 Super cartridges for competitive shooters.[1]

The 686 features a 6-round cylinder. The 686P variant, marketed as the Model 686 Plus, has a 7-round cylinder. The 686PP variant, with PP designating PowerPort, has an integral compensator (also known as a muzzle brake).

The 686 has been made with pistol grips having a squared or rounded end (colloquially, "square butt" or "round butt"). The grips on the pistol can be changed, and multiple after-market options are available.

The Model 686 has an adjustable rear sight, and until 1992, the 152 and 211 mm (6 and 8.325 in) versions had the option of an adjustable front sight. They had Goncalo alves hardwood grips until 1994, when the grip was replaced by a rubber Hogue grip.[1]

Through the years, there have been several variations on the Model 686. The Model 686 Classic Hunter was introduced in 1988 and has a 150 mm (6 in) barrel and a non-fluted cylinder; the Model 686 Black Stainless was introduced in 1989 and has either a 100 or 150 mm (4 or 6 in) barrel with a black finish, with production limited to 5000; the Model 686 National Security Special was introduced in 1992 and has a 76 or 102 mm (3 or 4 in) barrel; the Model 686 Target Champion was introduced in 1992 and has a 150 mm (6 in) match-grade barrel, adjustable trigger stop, and walnut grips; the Model 686 Power Port was introduced in 1994 and has a ported 150 mm (6 in) barrel; the Model 686 Plus was introduced in 1996 and has a 64, 76, 102, or 152 mm (2.5, 3, 4, or 6 in) barrel, adjustable sights, 7-shot cylinder, and Hogue rubber grips. As with all current Smith & Wesson revolvers, the 686 Plus now has a key lock integral to the frame of the gun.[1]

In 1987, seven years after the release of the Model 686, there were reports of cylinder binding with some types of standard .357 Magnum ammunition for L-frame revolvers manufactured before August 1987. S&W put out a product warning and authorized a no-charge upgrade to make modifications to the revolver. All recalled and reworked guns were stamped with an M marking, signifying that they had been recalled and fixed; thus it is known as the M modification for all 686, 686–1, 586–1, and 586-2 revolvers.[9]
