I have a leather IWB holster custom made for my (then EDC) S&W 39-2 by Seventrees in New York City in 1972 that is still in like-new condition. It has never stretched, absorbed any moisture, accumulated any interior dust or dirt, or adversely affected the pistol finish.
In 40 years the only care the leather has ever needed was a periodic coat of saddle soap and polishing with a soft cloth. I don't have my Milt Sparks and Ken Null horsehide leather holsters for such a long period of use but I'm sure that with similar care my grandsons will have use of them.
