The Taurus Model 66 is a medium-frame DA/SA revolver chambered in .357 Magnum with a 7-shot cylinder, a 6-inch barrel, and a black oxide steel finish. The 7-round capacity gives it one more round than most comparable revolvers.

Detailed Features 

The Taurus Security System (TSS) uses a key-operated lock that prevents the gun from firing or being cocked when engaged. The transfer bar mechanism blocks the hammer from contacting the firing pin unless the trigger is fully pulled, preventing accidental discharge. 
 
The DA/SA trigger allows deliberate single-action fire for accuracy-focused shots or faster double-action pulls for quick follow-ups. Fixed front sight and adjustable rear sight let you dial in accuracy at different distances. 
 

Usage Notes 

At 40 oz with the 6-inch barrel, this is a range and home defense revolver rather than a carry gun. The .357 Magnum chambering also accepts .38 Special, giving a lighter practice option. Rubber grips help absorb recoil from full-power .357 loads.

The Taurus 66 .357 Magnum with 6-inch barrel gets mixed feedback that's generally more positive than negative.

Build quality draws consistent praise. Owners describe it as solid and robust, and most report no significant deterioration with regular use.

The 6-inch barrel comes up as a specific accuracy advantage, with multiple reviewers citing good groups at extended range distances.

The 7-round cylinder is a genuine selling point for many buyers. One extra round over the standard 6-shot revolver gets mentioned as a practical advantage.

Versatility from being able to shoot both .357 Magnum and .38 Special is widely appreciated. Users like having a lighter, cheaper round for practice without needing a different gun.

Value perception is generally positive. Reviewers frequently compare it favorably to other revolvers in a similar price range.

On the negative side: trigger pull weight in double action draws the most criticism. A number of users find it heavier than expected, and some report it affected their accuracy until they adjusted technique. The black oxide finish gets occasional complaints about scratch resistance. Weight at 40 oz. is noted as a drawback for anyone thinking about carrying it. Taurus customer service experiences vary significantly among owners.
