I've been carrying my first 342Ti pretty much from when they were first introduced around 1998(?). Mostly in a pocket holster as an on duty BUG. I happened across another one a few years later, at a LGS, ANIB, and that's still in the box.
The first one was showing a lot of external wear and tear, so a few years ago I had it re-finished with Walt Birdsong's Black-T, still going strong! If it's not with me in a pocket holster, it's riding in an ankle rig...
