About
What it is, and why it matters
The Taurus Protector 651 is a medium-frame revolver chambered in .357 Magnum, manufactured by Taurus since 2001. Produced at Taurus's modern manufacturing facilities in São Leopoldo, Brazil and their American operations in Bainbridge, Georgia, this firearm reflects Taurus's commitment to delivering reliable firearms at competitive price points. The 5-round cylinder provides standard capacity for revolvers of this size class, while maintaining a compact profile suitable for concealed carry. The 2.0-inch barrel prioritizes concealability over sight radius. At 709g (25.0 oz) unloaded, this firearm provides a solid shooting platform that helps manage recoil during extended range sessions. Taurus has positioned this model as a high-value option in the competitive handgun market, offering features and reliability that punch above its price point, making it particularly appealing to first-time gun owners and experienced shooters seeking a reliable secondary firearm.
Taurus's revolver manufacturing expertise traces back to their acquisition of the Smith & Wesson factory in Brazil, giving them access to decades of refined revolver-building knowledge that continues to influence their designs today.
The Protector can safely chamber and fire .38 Special, .38 Special +P, and full .357 Magnum ammunition. The shrouded hammer design differs from the fully enclosed CIA models by still allowing manual cocking. Available in blue, matte blue, titanium, or stainless finishes.
