Description
Revolvers and .45 ACP have never played nicely together. For decades the only way to run the round in a wheelgun was fiddling with moon clips, and if you have ever bent one or dropped one in the dirt, you know the frustration. Charter Arms solved that with the Pitbull. A patented dual coil spring assembly built into the extractor grabs each rimless case at the chamber, so you load rounds straight in and kick the empties out with the ejector rod, no clips needed. It sounds simple, and that is the whole point.
Big Bore Muscle in a Carry-Sized Wheelgun
To handle the .45, Charter built the Pitbull on their extra-large stainless steel frame with a beefed-up cylinder, and the bolt notches are cut between the chambers rather than over them, which keeps the thinnest part of the cylinder wall away from the pressure. Even with the stout construction it comes in around 22 ounces with a 7.38 inch overall length, so it carries like a snub while hitting like a full-size. The 2.5 inch barrel wears a shrouded ejector rod, the sights are fixed and snag-free, and the full-size black rubber grip with finger grooves gives your hand something real to hold onto when the big bore barks.
Why the Pitbull .45 Makes Sense
The DA/SA action lets you run it double action in a hurry or cock the exposed hammer for deliberate single action shots. And if you already own a 1911 or another .45 pistol, ammo commonality is a genuine perk. One caliber to stock, one caliber to practice with, whether you treat the Pitbull as a backup, a nightstand gun, or your main carry piece.
American Made, Built to Work
Charter Arms has been building revolvers in Connecticut for over 50 years, and the Pitbull carries that no-frills, working-gun DNA. The matte stainless finish shrugs off sweat and weather, which matters on a gun that spends its life close to the body. If you want .45 ACP thump in a simple, reliable five-shot revolver, this is one of the very few games in town, and it does the job well.

Frequently Asked Questions
Does the Charter Arms Pitbull .45 ACP need moon clips?
No, and that is the whole reason this revolver exists. The Pitbull uses a patented dual coil spring assembly in the extractor that holds each rimless .45 ACP case at the chamber. You load rounds directly into the cylinder and eject empties with the ejector rod just like a rimmed cartridge revolver.
How heavy is the recoil on the Pitbull in .45 ACP?
At about 22 ounces, the Pitbull is light for a big-bore, so you will feel standard pressure .45 ACP, but the round is a pusher rather than a snappy one. The full rubber grip with finger grooves soaks up a good amount of it. Most folks find it more of a firm shove than a sting, and standard ball ammo makes for comfortable practice sessions.
Is the Pitbull a good match if I already carry a .45 semi-auto?
That is one of its best use cases. It shares ammo with your 1911 or other .45 pistol, so you only need to stock and train with one caliber. A lot of owners run it as a backup or secondary gun alongside a .45 semi-auto for exactly that reason.
Can the Charter Arms Pitbull be fired single action?
Yes. It has a standard exposed hammer and a DA/SA trigger, so you can pull straight through in double action or cock the hammer for a lighter, crisper single action break. That flexibility works well for both defensive use and slower paced range shooting.
