being the type of person that breaks a sweat reading a book or swimming, living in Fl, and likes leather holsters. I have similar problems. my edc is a 637-2 j frame and the wear esp on the top & grip strap is awful. that's why I carry that instead of the s/s 640 no dash with presentation grips that I much prefer but would not be happy if I got any marks on it. not only do I sweat thru my clothes and boots but also belts and holsters. carrying a gun of any finish in a leather holster that has absorbed salt is not a great idea and special care and treatment of the gun and belt/holster is needed. padded nylon isn't much better imo and I hate plastic, but gotta give props to the safariland drop down retention 3 thigh holster. mostly plastic & nylon it is comfortable, works very well but I still kinda feel a bit like a Mall Ninja even though I ONLY use it in the field.
