The Charter Arms Target Mastiff is a semi-automatic pistol chambered in 9mm Luger, built on a stainless steel frame with a black nitride finish. The 6-inch barrel gives it a longer sight radius than most compact pistols, and the Picatinny rail makes optic mounting straightforward. It ships new in box with a 5-round capacity and a black rubber grip.

Detailed Features 

 
The stainless steel frame and barrel hold up well to regular use, and the black nitride finish adds corrosion resistance without changing the dimensions. The Picatinny rail accepts red-dot sights and similar optics, which helps compensate for the pistol's lower-than-average round count. Black rubber grips reduce slippage during firing and soften felt recoil modestly. 
 
The standard trigger is consistent across the pull, which suits shooters who prefer a predictable break over a short, light pull.

Users discussing the Charter Arms Mastiff 9mm generally land in cautious-positive territory.

The black nitride finish is a common point of praise: owners note it holds up well to regular handling and hasn't shown wear after extended use. The 6-inch barrel gets credit for accuracy at range distances, and several shooters with smaller hands mention the grip size and recoil level work well for them.

On the negative side, the weight draws complaints from people comparing it to other 9mm semi-autos of similar size. The 5-round capacity is the most frequently cited drawback versus the broader market. A handful of owners reported feeding or ejection failures during early break-in, though most say reliability settled down after the first few hundred rounds.

Overall the Mastiff tends to appeal to shooters who prioritize the longer barrel and build quality over capacity.
