Can't speak as to Bud's, at least not until my M10 3" I ordered from them the other day shows up--but I do know what police and security Model 10s generally are like. Good project guns: the ones I have seen have been older pre-Model 10s from the early 1950s with a LOT of carry miles on them, and enough banging on doorways to make right side grip panels noticeably battered. The backstraps and top rear of the frames are usually nicely browned and very slightly pitted from exposure to the elements and they have about 80% blue remaining. Plus miscellaneous nicks and dings.
The good news is that they were usually minimally maintained, infrequently fired with standard velocity factory loads, and somewhat regularly inspected and cleaned. Best of all, regulations forbade people from taking off the side plates and screwing around with the actions to "improve" them. Bores, lockup and timing have usually been fine. The worst I have found inside has been 50 years worth of dried grease and dirt.
I usually do a good cleaning, fit up a spring kit, smooth the grooved triggers, and replace the stocks. That done I have a dandy utility gun of excellent quality that fires a great cartridge and will outshoot almost anything else all day long. Best bang for the buck around. The more I shoot them the more respect I have for the people who built them and carried them. Not fancy, but better guns were never made.
