Among the most respected names in revolver manufacturing, Smith & Wesson stands tall. Two of their most iconic models, the Model 66 and the Model 686, represent the pinnacle of revolver engineering, each possessing unique characteristics that cater to different shooters and their needs. This article dives deep into the S&W 66 vs 686 debate, offering a comprehensive comparison to help you understand the nuances of these classic firearms. Whether you’re a seasoned collector or a newcomer looking to purchase your first revolver, this comparison is designed to guide you through the features, performance, and ideal applications of these magnificent guns.

To appreciate the S&W 66 vs 686 distinction, it’s essential to understand the historical context. Smith & Wesson’s journey began in 1852, born from a vision to revolutionize the firearms industry. Their innovative approach, combined with unwavering commitment to quality, quickly established them as a leading manufacturer of revolvers. Through the decades, Smith & Wesson continuously refined their designs, introducing a series of models that became legendary in their own right. The Model 66 and the Model 686 are direct descendants of this rich history.

The Model 66, a significant piece of history, traces its lineage back to the Model 19, a blued steel revolver that gained fame as the “Combat Magnum” due to its ability to handle the powerful .357 Magnum cartridge. The Model 66 followed, bringing the same performance to the table but utilizing stainless steel for improved corrosion resistance and ease of maintenance. This made it an ideal choice for law enforcement officers and civilians alike, and is still a beloved firearm in the modern era.

The Model 686, on the other hand, emerged as a natural evolution. The Model 686 embraced a larger frame design, strengthening its durability and the ability to withstand high-volume shooting, while also making the gun better able to handle recoil. This design choice gave the Model 686 a reputation for being a robust and reliable firearm. These histories, coupled with continuous refinements over the years, solidify the Model 66 and Model 686 as enduring symbols of Smith & Wesson’s commitment to excellence.

Dissecting Frames and Their Construction

The frame size plays a pivotal role in determining the feel and performance of any revolver. In the S&W 66 vs 686 context, the K-Frame of the Model 66 and the L-Frame of the Model 686 present distinct advantages.

The K-Frame of the Model 66 offers a blend of compactness and comfortable handling. Its slightly smaller size makes it easier to carry concealed, especially when paired with a suitable holster. The K-Frame allows for a natural point of aim and a balanced feel in the hand, making it suitable for a wide range of shooters. However, the K-Frame is more susceptible to wear and tear under sustained use with potent .357 Magnum loads. While robust, its lighter construction is ultimately challenged by the intense forces generated by heavy ammunition.

In contrast, the L-Frame of the Model 686 represents a significant step up in terms of strength and durability. This frame is larger and more robust, allowing it to handle a greater volume of shooting, including prolonged sessions with .357 Magnum cartridges. The added weight of the L-Frame assists in controlling recoil, making the Model 686 a more comfortable option for extended shooting at the range. It is also typically more resistant to damage over time. This difference in design is crucial to the S&W 66 vs 686 discussion, as it dictates the weapon’s longevity.

Ultimately, the choice between the K-Frame and the L-Frame boils down to the intended use. If concealed carry is a primary concern, the lighter and more compact K-Frame may be preferable. For those seeking a workhorse revolver that can endure frequent use and handle powerful loads, the L-Frame is the clear winner.

Assessing Performance and Ergonomics

The handling characteristics are another essential area of comparison within the S&W 66 vs 686 argument. Recoil, accuracy, trigger feel, and overall handling all contribute to a revolver’s usability.

Recoil:

The Model 66, due to its lighter K-Frame design, tends to exhibit more felt recoil than the Model 686. The .357 Magnum cartridge, known for its impressive power, generates significant recoil. The lighter frame of the Model 66 results in more of this force being transmitted to the shooter’s hand. The Model 686, with its heavier L-Frame, absorbs more of the recoil, resulting in a noticeably softer shooting experience.

Accuracy:

Both the Model 66 and the Model 686 are capable of delivering exceptional accuracy. The barrel length and sights influence the accuracy potential. Longer barrels generally promote increased sight radius and greater stability. The sight picture, along with a consistent trigger pull, can greatly affect the shooter’s ability to group shots.

Trigger Pull:

The trigger pull on both models is generally smooth and predictable, whether firing in single-action or double-action mode. Some owners might choose to have their triggers worked on professionally for further refinement. The trigger contributes to the overall shooting experience, and the better the trigger, the better the shot.

Overall Handling:

The feel of each revolver in the hand is a crucial element. The Model 66, being slightly smaller and lighter, is known for its maneuverability and balance. It feels more compact and agile, making it easy to draw and point quickly. The Model 686, while heavier, offers a more substantial feel and a secure grip. The added weight contributes to its stability.

Considering Reliability and Endurance

Reliability is paramount when choosing a defensive firearm. The stainless steel construction of both the Model 66 and Model 686 offers exceptional resistance to corrosion and wear, ensuring their longevity. Both models are renowned for their dependability, and regular cleaning and maintenance will promote a long service life. The L-Frame of the Model 686 has a slight edge in terms of durability. Its sturdier construction is built to withstand heavier use and higher round counts. The S&W 66 vs 686 consideration here highlights the importance of intended use, with the 686 being the ideal choice for those seeking a firearm that can withstand intense use.

Ammo Choices: .357 Magnum and .38 Special

The .357 Magnum and .38 Special are the primary cartridges compatible with both the Model 66 and 686, presenting various options for the shooter. The .357 Magnum is a powerful cartridge offering exceptional stopping power. It delivers a higher muzzle velocity and greater energy than the .38 Special. The .38 Special, conversely, is a milder option that’s easier to handle and control, making it great for target practice. The .38 Special is typically more cost-effective and has less recoil.

For self-defense applications, the .357 Magnum is a great choice for its immense stopping power. If you are looking for less felt recoil and a more affordable round, the .38 special might be the right fit. When discussing the S&W 66 vs 686, ammunition selection should be based on your intended use.

Identifying Ideal Use Cases

Deciding between the S&W 66 vs 686 depends on what the revolver will be used for.

Model 66:

The Model 66, thanks to its comfortable balance and size, is well-suited for concealed carry. Its compact design makes it easier to conceal under clothing. It is also a great option for home defense and target shooting.

Model 686:

The Model 686, built for heavy duty, is a preferred choice for home defense, hunting, and range shooting. Its robust L-Frame and the availability of longer barrels make it suited for these uses. Some Model 686 variants, specifically those with longer barrels, might be suitable for hunting smaller game.

Summarizing the Pros and Cons

Here’s a quick look at the advantages and disadvantages of both models:

Model 66:

Pros: Compact and easy to carry, well-balanced, known for good handling.

Cons: More felt recoil, slightly less robust frame.

Model 686:

Price, Market Availability, and Considerations

The price and availability of these models play a part in the buying decision. The Model 66 and Model 686 can be found in new and used conditions, varying in price depending on condition, features, and market demand. The best way to know the exact price is to look at retailers, as they are subject to change. Availability of these models can vary; collectors often seek older Model 66s.
