The Charter Arms Pitbull is a .40 S&W double/single action revolver with a 2.3-inch barrel, 5-round capacity, and 20 oz weight. The stainless steel frame is notable for its ability to chamber rimless .40 S&W cartridges without moon clips, which sets it apart from most revolvers in this caliber.

Detailed Features: 

The full hammer block safety system prevents discharge unless the trigger is fully pressed. The rubber grips with finger grooves keep the revolver stable through follow-up shots. Fixed front sight keeps target acquisition straightforward. The aluminum frame combined with the stainless cylinder and barrel balances portability with structural durability. 
 
The rimless cartridge capability is the defining feature here. Typical revolvers require moon clips or a rimmed cartridge, but the Pitbull chambers .40 S&W directly, which simplifies reloading from semi-auto magazines in a pinch. 
 

Target Audience: 

This revolver fits people who want the simplicity and reliability of a revolver action but prefer the .40 S&W caliber they may already carry in a semi-automatic. It works for concealed carry and home defense with equal practicality. 
 

Usage Scenarios: 

The 2.3-inch barrel and 20 oz weight handle well under clothing without printing excessively. At the range the manageable size pairs reasonably with the .40 S&W's recoil, though the lightweight frame makes it more noticeable than a full-size gun. For home defense, the simple operation means quick deployment under stress.

The Pitbull's moonclip-free .40 S&W chambering is its most distinctive selling point, and owners who value that convenience come back to it consistently in reviews. Lightweight design and compact dimensions are cited as advantages for concealed carry throughout the day.

Criticism centers on three areas. Trigger pull runs heavy compared to many competing revolvers, and some shooters find it less smooth than they'd like. The lightweight frame amplifies .40 S&W recoil more than a steel-frame revolver would, which affects comfort during extended range sessions. A handful of users also note fit and finish variability between units. Overall the Pitbull lands as a practical carry option for people specifically seeking a .40 S&W revolver, but those without that specific caliber preference may find other options more refined.
