The Charter Arms Mag Pug is a compact .357 Magnum revolver that also accepts .38 Special. The 2.2-inch barrel keeps total length to 7.25 inches, and the 23-oz stainless steel frame makes it light enough for daily carry. Capacity is 5 rounds. The black rubber grips have finger grooves, and a transfer bar safety prevents accidental discharge.

Detailed Features 

The double/single action mechanism covers both deliberate precision shots and quick double-action draws. Fixed front sights provide a consistent reference point. The rubber finger-groove grips help control the significant recoil .357 Magnum generates from a sub-3-inch barrel. At 7.25 inches overall, it conceals without difficulty under a cover garment. 
 

Target Audience 

Carry-focused shooters who want .357 stopping power in the smallest possible package. Also useful as a backup gun for those who already carry a primary sidearm. 
 

Usage Scenarios 

Concealed carry is the obvious application. At the range, running .38 Special loads keeps recoil manageable for practice; stepping up to full-power .357 for the carry cylinder is straightforward.

The Charter Arms Mag Pug .357 draws predictable feedback given its design brief: maximum power in minimum size.

Owners who bought it for concealed carry or as a backup gun generally appreciate the compact dimensions and the .357 Magnum chambering. The transfer bar safety and general reliability under normal conditions come up positively. The short overall length is the primary selling point, and most buyers find it delivers on that.

The consistent criticisms are recoil and trigger pull. A short, light stainless frame with a 2.2-inch barrel transmits full-power .357 loads forcefully, and extended range sessions with hot ammunition can be fatiguing. Some shooters find the double-action pull heavier than they prefer, which affects accuracy during rapid fire. A few buyers also wish the fit and finish were more refined.

In practice, this is a purpose-built carry revolver rather than a range gun. Those who understand that going in tend to rate it well.
