About This Firearm

The 686 Plus is Smith & Wesson's answer to a simple question: why not 7 rounds? Built on the L-Frame, this revolver holds one more round than the standard 686 without changing the external dimensions. The 9.56" overall length and 39.2 oz weight are identical to the 6-shot version, but that extra chamber puts it in a class of its own among production .357 revolvers. Only the S&W TRR8 (8 rounds, N-Frame) holds more, and that gun is considerably larger.

The 4" barrel with full underlug gives the 686 Plus enough weight forward to settle between shots. Owners on forums consistently describe the L-Frame action as smooth from the factory, and it only gets better with a spring kit or dry-fire time. The adjustable white outline rear sight paired with the red ramp front is easy to pick up in most lighting conditions. The stainless steel frame and barrel handle a lifetime of full-power loads without concern.

The L-Frame 686 has been the benchmark .357 revolver since 1981. The "Plus" variant with its 7-round cylinder is the version most people should look at unless they specifically need the thinner cylinder profile of the standard 686. That seventh round is free capacity with no real trade-off in size or handling. The Ruger GP100 is the closest competitor and runs about 0.8 oz heavier at 40 oz, but stays at 6 rounds.

Best For

GOOD
Range / Training
At 39.2 oz with a 4" barrel, the weight absorbs .357 Mag recoil well enough for extended sessions. The adjustable sights let you zero for different loads. Owners regularly report shooting 200+ rounds of full-power magnums in a session without fatigue.
GOOD
Home Defense
Seven rounds of .357 Mag in a gun that weighs 39.2 oz. The L-Frame action runs smoothly in double-action, and the red ramp front sight is visible in low light. Loaded with .38 Special +P, recoil drops to minimal levels for anyone in the household who needs to use it.
FAIR
Hunting
The 4" barrel gives up roughly 50-75 fps compared to 6" options like the Colt Python. Enough for deer inside 50 yards with proper loads, but the S&W TRR8 with its 5" barrel and 8-round cylinder is better suited to field work if hunting is the primary use.

Strengths & Limitations

Strengths
  • 7-round cylinder in the same L-Frame dimensions as the standard 6-shot 686. One extra round with no increase in size or weight.
  • The stainless steel construction handles an unlimited diet of full-power .357 loads. Owners with 10,000+ round counts report no timing or lockwork issues.
Limitations
  • The internal lock above the cylinder release is a persistent sore point. While documented lock failures are rare, many owners remove or pin it on principle.
  • The synthetic grips that ship from the factory are widely considered a placeholder. Most owners swap to Hogue, Pachmayr, or wood grips within the first month.

Frequently Asked Questions

Is the Smith & Wesson 686 Plus safe to dry-fire?

Yes. The 686 Plus uses a firing pin mounted in the frame with a transfer bar safety. Dry-firing will not damage the gun. Many owners dry-fire regularly to smooth the double-action pull, and S&W's own documentation confirms it is safe without snap caps.

What is the difference between the 686 and the 686 Plus?

Cylinder capacity. The standard 686 holds 6 rounds, the 686 Plus holds 7. External dimensions, frame size (L-Frame), barrel options, and action are identical. The Plus cylinder is bored for the extra chamber but does not change the overall width or handling.

Does the 686 Plus work well with .38 Special?

All .357 Mag revolvers fire .38 Special safely. The 686 Plus at 39.2 oz makes .38 Special feel almost like a .22 in terms of recoil. Many owners keep it loaded with .38 Special +P for home defense and save .357 Mag for range days or woods carry.
