What are the pros and cons of the Smith & Wesson Model 66?
Having handled many of these through FFL transfers, I can tell you these are solid revolvers, but they aren’t without their quirks as trade-ins.
- ✅ Durability: Stainless steel construction means it’s built to last and resist corrosion, even after years of service.
- ✅ Reliability: Revolvers are inherently reliable, and the Model 66 is no exception. It cycles consistently, a major plus for a defensive firearm.
- ✅ Versatility: The ability to shoot both .357 Magnum and .38 Special makes it adaptable for different shooting scenarios and recoil preferences.
- ✅ Value: As a police trade-in, you’re getting a high-quality, American-made firearm at a significantly reduced price compared to a new equivalent.
- ✅ History: Owning a police trade-in connects you to a piece of law enforcement history, offering a unique story behind the gun.
- ❌ Cosmetic Wear: Being a used police firearm, expect holster wear, dings, and scratches. These are not pristine guns.
- ❌ Trigger Pull: While generally smooth, some trade-ins might have a heavier or less refined double-action trigger pull compared to a custom-tuned revolver.
- ❌ Limited Capacity: Six rounds is standard for revolvers but less than most modern semi-automatic pistols (see our high-capacity pistols).
How does the Smith & Wesson Model 66 compare to other revolvers?
When you’re looking at a .357 Magnum revolver, especially a trade-in, it’s helpful to see how it stacks up against others on the market, both new and used.
| Feature | Smith & Wesson Model 66 Police Trade-In | Taurus 605 (.357 Mag) | Ruger GP100 (.357 Mag) |
|---|---|---|---|
| Material | Stainless Steel | Stainless Steel / Carbon Steel | Stainless Steel |
| Quality | Excellent (used, but robust S&W build) | Good (modern production, some variability) | Excellent (rugged, overbuilt design) |
| Compatibility | .357 Mag / .38 Spl | .357 Mag / .38 Spl | .357 Mag / .38 Spl |
| Condition | Used (Police Trade-In) | New | New |
| Lifespan/Durability | Very High (built for duty) | Moderate to High | Very High (known for extreme durability) |
| Price | ~$299.00 | ~$350-$450 | ~$700-$900 |
The Model 66 trade-in offers a sweet spot of classic S&W quality and durability at a price point that’s hard to beat, often undercutting even new budget options like the Taurus, while offering a similar level of build quality to the more expensive Ruger GP100, albeit in a used condition.
Frequently Asked Questions about the Smith & Wesson Model 66 .357 Mag Police Trade-In
What condition are these police trade-in revolvers in?
Our Smith & Wesson Model 66 police trade-ins are generally in good to very good functional condition. Cosmetically, expect holster wear, minor dings, and finish imperfections consistent with a firearm that has seen active duty. We inspect each one to ensure it’s mechanically sound before listing.
Can I use both .357 Magnum and .38 Special ammunition in this revolver?
Yes, the Smith & Wesson Model 66 is chambered for .357 Magnum but is fully capable of safely firing .38 Special ammunition. This gives you flexibility for practice with lower recoil and cost, or for full-power defensive loads.
Is this model suitable for concealed carry?
While the Model 66 is a K-frame revolver, which is a medium-sized frame, its suitability for concealed carry depends on the barrel length and your body type. Shorter barrel models (2.5″-3″) are often carried, while longer barrels (4″+) might be better suited for open carry or home defense. It’s a bit larger than many modern compact semi-autos.
What is the recoil like with .357 Magnum in the Model 66?
Recoil with full-power .357 Magnum loads in the Model 66 can be stout, especially with lighter grips. The stainless steel frame helps absorb some of it, but it’s a powerful cartridge. Shooting .38 Special is much milder and makes for more comfortable practice.
Does this come with original accessories, like the box or manual?
Typically, police trade-in firearms do not come with their original boxes, manuals, or accessories. They are usually shipped as the firearm only. We recommend consulting online resources for manuals or purchasing aftermarket accessories as needed.
Where can I buy revolvers online?
You can purchase revolvers online right here at Kansas Gunshop (kansas-gunshop.com). We offer a selection of new and used firearms, and we’ll facilitate the FFL transfer to your local dealer.
What is an FFL transfer and how does it work?
An FFL (Federal Firearms License) transfer is the process required by law for all firearm purchases made online. You buy the firearm from us, and we ship it to a licensed FFL dealer in your state. You then visit your chosen FFL dealer, complete the necessary background checks (like the NICS check), and take possession of your firearm. We’ll guide you through the process.
