I have a nice 5 screw Pre 28, 4" (SN 1266xx) that is in decent shape, but it's definitely seen some use in its day. The finish is far from pristine, but it's not exactly rough either.
Would you hesitate to use this for a regular shooter or carry? It would see weekly range use and occasional carry on hikes, fishing, etc.
I typically load lower power .38s for range use.
If I decide it's too "good" to carry, then I'll likely stop shooting it all together and practice with the GP100 that would replace it.
