The Charter Arms Target Mastiff is a double-action-only revolver chambered in .357 Magnum, also compatible with .38 Special. The 6-inch barrel and Picatinny rail for optic mounting distinguish it from Charter Arms' carry-oriented lineup, positioning it as a target and range-focused revolver.

Features 

The stainless steel frame with black nitride finish on the barrel and cylinder provides good corrosion resistance and a practical matte appearance. The Picatinny rail allows direct mounting of red dot sights, which is the main feature differentiating this from a standard Target Mastiff configuration. The 6-inch barrel extends the sight radius and improves velocity compared to shorter Charter Arms models. Black rubber grips are comfortable and absorb some recoil. The exposed hammer allows single-action cocking for enhanced shot-by-shot control. 
 

Usage 

The .357 Magnum in a 6-inch barreled revolver is well suited for target shooting and range work. The DA-only configuration with an exposed hammer that allows SA mode is slightly unusual. The exposed hammer permits manual cocking for single-action precision shooting, while the internal mechanism is double-action only when the hammer is not manually cocked. Charter Arms offers good value for buyers who want a revolver without paying premium prices. The optic rail makes this useful for those who want to run a red dot on a mid-priced .357.

Owners of the Target Mastiff appreciate the build quality for the price. Charter Arms positions this at a more accessible price point than comparable Smith & Wesson or Ruger .357 revolvers, and most buyers find the construction adequate. Trigger pull and accuracy with .357 Magnum rounds get positive marks, and the 6-inch barrel length is favored by target shooters for the added precision.

The optic-ready rail is well-received. It's a practical feature at this price that opens up red dot mounting without gunsmithing. Weight is noted as heavier than expected by some buyers, which can cause fatigue in extended range sessions. Recoil with full-power .357 Magnum loads is substantial; most owners recommend starting with .38 Special or lighter .357 loads to build proficiency. Aftermarket parts availability and holster options are more limited than for major brands, which comes up occasionally in owner discussions.
