well especially since I've been reading about the bullet case hitting the slide stop, and Kahr sending out new slides, slide stops, and springs...I would definately wait until I made sure the known issues were out of the way, before getting a refinish done.
But I just didn't want the slide refinish to void my entire warranty simply due to a 40 dollar external upgrade.
If you say that some of these aftermarket finishes are thicker, that could be a problem, since I've heard that the polymer overmold around the slide rails is really tight, as things are.
