I had a customized one not too long ago. Bobbed hammer, slicked up, new springs, etc. It was engraved "Terminator" or something like that. I swapped it even for a minty old SB Model 36 and was happy with the deal. My wife liked it, but I was never quite sold on the concept. I've had two of the Charter .44s over the years. The other was a pug. I still have one of the Rossi 720s that I'll probably trade off.
Even in custom format, the erratic QC of Charter over the years left me a bit uneasy. I also found them to be a bit snappish. My wife liked the Charter .44s a lot though and yelled at me for swapping them off.
.44 Special ammo has unfortunately become increasingly hard to find and expensive. I always liked the Blazer JHPs though.
