My M9-A1 has been in a leather holster maybe 3 times and it has what can only to be finish wear (color of the finish is lighter) on the top and slide near the muzzle. :? The holster does fit a bit tight; the gun won’t fall out if you shake the holster upside down. I don’t have any other holsters so don’t know if that is too tight or not. But I doubt holsters should be loose.
