I own a Charter Arms Pitbull 5" stainless.
Great gun, just wish we had a speedloader available I'd get much more use out of it if we did.
Quite accurate with 147gr handloads, plenty accurate with 124. I don't shoot 115 so cannot comment.
Have put around 300-500 rounds through mine.
Had a rear sight come loose and dissappear, Charter Arms sent me replacement parts as soon as I called them and were fantastic to deal with. Don't believe everything you read on the interwebz.
Yes headspace would be set by ejector star.
It uses spring loaded pieces in ejector to lock into rim of brass to keep in gun and to push the cartridge out when ejected.
Lots of info out there on them. With lots of users saying the design doesn't work etc. After an initial break in and cleaning mine has been running flawlessly for hundreds of various rounds.
The alfa proj in 9mm requires moon clips for ejecting. Otherwise you might have to poke the empty cases out of the cylinder. If this is a deal breaker the charter might be the better option.
Moon clips are like cheap speed loaders, so if you like to reload quickly the alfa is probably the better choice.
Spring kits exist for the alfa to make the DA trigger better. No idea if the same exists for the charter.
I've shot the Alpha and it was fine, though I'd really like a S&W 929. I hear the moonclips are hard (impossible) to find.
The old and long out of production S&W 9mm used the springs that lock into the ejector grooves as well.
