CJF, yes the original model 60 will handle +P loads without a
problem. However, I advise against a steady diet of those
rounds, cuz the original's (Chief's Special w/R prefix) have
been discontinued. Also, just FYI when referring to a weapons
serial number please only give the fist few didigits, such as
J123XXX. That way the complete S/N remains confidential
to the owner.
