Smith & Wesson L Frame Model 586 4" Barrel — Non-Pinned, .357 Magnum, Red Ramp Front Sight, Used

Part #58621A | Used | L Frame | Model 586 | 4" Barrel | Non-Pinned | .357 Magnum | Red Ramp Front Sight | Blued

Genuine used Smith & Wesson blued 4" barrel for the L Frame Model 586 Distinguished Combat Magnum in .357 Magnum. This barrel features the factory red ramp front sight insert — a serrated ramp with a red plastic insert for improved sight acquisition. Buyers specifically replacing a chipped, faded, or missing red ramp insert will want to verify the front sight condition before purchasing; contact us for photos.

This is a non-pinned barrel — post-approximately 1982 production, retained by thread tension only without a cross-pin through the frame. Non-pinned and pinned barrels are not interchangeable; verify your revolver’s production configuration before ordering.

The Model 586 Distinguished Combat Magnum was S&W’s blued L Frame .357 Magnum, introduced in 1980 alongside the stainless Model 686, and discontinued in 1999. The 4" barrel was the primary duty and service configuration. Used 586 barrels in good condition are increasingly scarce as the model ages out of current production.

Used Condition: Genuine used OEM barrel. Expect normal handling marks, holster wear, and finish wear consistent with a used service barrel. Red ramp front sight insert present. Inspected for mechanical soundness — no cracks, bulges, or forcing cone damage observed. Cosmetic and finish condition varies — contact us for photos before purchasing if condition is a concern.

Compatible Models

  • Model 586 — L Frame .357 Magnum blued, 4" non-pinned (post-~1982 production)
  • Model 686 (verify fitment) — L Frame .357 Magnum stainless; shares the same L Frame barrel profile for 4" non-pinned; finish will not match (686 is stainless); confirm timing with your gunsmith
