I know which of them I would zero in on, and have- Colt Woodsman, OM, and S&W K-22(M17). I know why I did but to make a pronouncement for another guy I would need to know where his head is at. They're all top-tier guns IMO and will all function well and return a long service life if properly maintained and not abused. As for parts availability in the unlikely event of breakage, everything is out there, for a price.
