Sergio, depends on the kind of leather tanning, or on the fact that it's been oiled regularly? German holsters were vegetable tanned. Nothing terribly toxic about it. Most pistols are irregularly oiled to be sure..I figure once a year is not that often?
There are pro's and con's about storing in a holster. Ten years ago I decided to test it out. Maybe in another ten years I can say for sure...
One thing I can attest to right now. Storing a pistol in a holster isn't good for the holster. The weight puts stress on the belt loop bends if it's stored flat. They have a tendency to crack at the top bend. Inserting the pistol wears both the pistol and holster. I store this one on edge...Don't get me wrong. I am not recommending storing a pistol in a holster cause it's better not to. I was just interested to know IF it hurts the finish. So far I can't see where it has in this case. Now..IF the holster got wet somehow..it all changes.

That's why I was interested to know IF this pistol was found in the holster.
