The Charter Arms Mag Pug & Pit Bull Combo is a double/single-action revolver that ships with an additional cylinder, letting you run .357 Magnum, .38 Special, or 9mm depending on which cylinder is installed. The stainless steel frame keeps weight at 23.0 oz with a 2.2-inch barrel.

Features 

The transfer bar safety reduces the risk of accidental discharge if the gun is dropped. Fixed sights are durable and work well at the short distances where a 2.2-inch barreled revolver is most useful. The multi-caliber setup is the main selling point: .357 Magnum for heavier work, .38 Special for training or lower recoil, and 9mm if that is what you have on hand. Cylinder swaps require the appropriate corresponding cylinder.

Charter Arms revolvers attract a crowd that wants solid carry performance without paying premium prices, and the Mag Pug & Pit Bull Combo fits that profile. The compact size and stainless finish get consistent positive marks, and the multi-caliber option is genuinely useful rather than a marketing footnote.

The main criticism across user feedback is trigger pull weight. Double-action pull on Charter Arms revolvers runs heavier than some competitors, which takes getting used to and can affect accuracy for newer shooters. Fit and finish comments vary — most find it acceptable for the price, though the occasional quality-control issue gets mentioned.

Recoil in .357 Magnum from a 23-ounce gun with a short barrel is substantial. Owners who fire a lot of full-power Magnum loads usually end up adding aftermarket grips. The aftermarket for Charter Arms is thinner than for S&W J-frames, which comes up when buyers start looking for accessories.
