Detailed Features 

The black nitride finish is durable and corrosion-resistant. Fixed front sights keep target acquisition fast without requiring adjustments. The finger-grooved rubber grip gives a positive hold and some cushioning against the .40 S&W recoil in a 1.3-lb frame. 
 
The DA/SA action provides flexibility — double-action for a consistent first pull, or single-action once the hammer is manually cocked for more precise shots. The Pitbull's design allows it to use rimless .40 S&W cartridges in a revolver format, which is the notable engineering feature of this model. 
 

Target Audience 

Suited for concealed carry users who prefer revolver mechanics but want to shoot a .40 S&W cartridge. Also works for recreational shooters curious about the platform. 
 

Usage Scenarios 

• Home Defense: Compact storage with reliable revolver operation. 
• Concealed Carry: Lightweight at 1.3 lbs with a streamlined profile. 
• Recreational Shooting: Manageable for range practice, though the .40 S&W in a light snub-nose produces noticeable recoil.

The Charter Arms Pitbull in .40 S&W gets a generally positive but nuanced reception.

The compact size and 1.3-lb weight are the most consistently praised features. Owners who carry it appreciate how easily it disappears under clothing. The DA/SA capability is seen as useful, and the ability to run .40 S&W cartridges through a revolver is viewed as a genuine differentiator from other compact revolvers.

Reliability gets solid marks overall, with most owners reporting dependable function. Recoil is the main trade-off — .40 S&W in a 1.3-lb frame is sharp, and some shooters find the Pitbull uncomfortable for extended range sessions. This comes up more from newer shooters or those not accustomed to the caliber.

Critiques include a heavier-than-expected trigger pull in double-action mode, and some comments about finish quality not matching higher-end options. Five rounds is a known limitation compared to semi-automatics. Finding holsters specifically designed for this model can be tricky given its niche status.

The price point is considered fair for what it offers, and most buyers who wanted a compact .40 S&W revolver find it meets that specific requirement.
