SC State Troopers carried S&W Model 65's for a number of years, then adopted the Glock 22, then in the past year or so adopted the Glock 37 in .45GAP. It would be relatively easy to pick up a Model 65 or Glock 22 with the SC markings. The 65's had a rollmark on many, either SCHP or SCHD I believe. The Glock 22's were in a special serial number range, something like SC***, or something similar, so they are easily identifiable. I have seen both of these for sale often in SC, since the state traded them in towards new weapons. They also traded off a bunch of Remington 870's a couple years ago. Some were almost new, others were well worn. I had one like new roll marked SCHP. These are also common in SC.
