Welcome to the forum.
I've owned my P239 for at least five years or more. It sees a lot of time in and out of the holster. It is the one firearm that gets sot EVERY time I go to the range no matter what else I'm shooting.
The finish on mine is holding up very well. I carry it it both a Milt Sparks leather holster and a Kydex. I've shot it in competition as well. Almost no wear showing thus far.
It's also one accurate little handgun even in .40 S&W. I love it and will never part with it.
