Taurus 66 Combat
The Taurus 66 Combat is a purpose-built everyday carry revolver chambered in .357 Magnum, holding seven rounds where most medium-frame revolvers hold six. Built on the proven M66 platform, the 66 Combat adds a bobbed DAO hammer, a fiber-optic front sight, a drilled-and-tapped top strap that accepts an RMSc optic plate (included), and a set of round-butt Hogue rubber grips for snag-free concealment. At $973 MSRP with all-stainless construction, it’s the most feature-complete defensive revolver Taurus has ever produced — and one of the most capable mid-priced revolvers on the market.

Why Seven Rounds? What Makes the 66 Combat’s Cylinder Unique
Taurus redesigned the M66 cylinder to fit seven charge holes in the same frame space as a standard six-shot revolver. More than just extra capacity, the new geometry repositions the cylinder locking slots between the charge holes rather than adjacent to them — leaving more stainless steel between the locking slots and charge holes for added structural strength. The result is a revolver that’s simultaneously stronger and higher-capacity than its predecessor. Compatible with S&W 686+ seven-shot speedloaders, the 66 Combat lets you use existing aftermarket reloading gear.
Taurus 66 Combat Specs: Dimensions, Weight, and Trigger
The 66 Combat wears a 3” stainless steel barrel — the classic FBI-tested balance point between portability and .357 Magnum velocity. Overall length is 8.4 inches, height is 5.67 inches, and width is 1.52 inches. The all-steel construction brings total weight to 2 lbs. 5 oz. — enough mass to tame .357 Magnum recoil without becoming impractical to carry. The DAO trigger measured 10 lbs. 1 oz. in independent testing — smooth for a stock revolver and appropriate for a dedicated carry firearm.
Optics-Ready Top Strap: What Fits the Taurus 66 Combat?
The 66 Combat arrives with an RMSc-footprint optic adapter plate pre-installed in the box. The top strap is drilled and tapped to accept this plate, which accommodates any optic using the RMSc footprint — including the Shield RMSc, Holosun EPS Carry, and Vortex Defender CCW. When shooting without an optic, the fiber-optic front sight indexes against a serrated groove machined into the top strap. Note that the front fiber optic does not co-witness when an optic is mounted, so red-dot users will rely entirely on the electronic sight.
Taurus 66 Combat vs. S&W 686: Which .357 Revolver Should You Buy?
The S&W 686 is the benchmark .357 medium-frame revolver and typically runs $150–$200 more than the 66 Combat. The 686 offers adjustable sights and a longer track record; the 66 Combat counters with a smoother DAO-optimized trigger, factory optics capability, and a seventh shot in the same frame. If you carry a .357 revolver and want modern features like a red dot and snag-free DAO hammer, the 66 Combat is the better choice. The 686 remains the pick for range work and adjustable-sight precision.
.38 Special or .357 Magnum for Carry: What to Feed the 66 Combat
The 66 Combat is chambered in .357 Magnum and accepts all .38 Special and .38 Special +P loads. For everyday carry, most shooters will choose a quality .357 Magnum defensive load like Speer Gold Dot 135 gr. +P or Federal HST 130 gr. The 3” barrel sacrifices some velocity compared to a 4” tube, but delivers adequate expansion performance from modern hollowpoint loads. For practice, running .38 Special +P through the 66 Combat keeps the session productive and affordable without the added fatigue of full-power .357 Magnum round after round.
