I thought the Bulldog Pug 44 was a made by Charter?  If so, then any holster made for a Colt detective 6 shot will fit in the correct barrel length.  You can use a holster for an S&W K frame.  They are a little loose, but you can tighten up the retaining strap.  I'm using one now for my Charter for belt carry and a Blade-tec IWB made for a Colt for concealment.  44 Man
