Well I tried some wax, that worked for a few days, I have a bar of wax and I rubed it in the leather. But I noticed the gun had wax on it each time I pulled it out, and lastngiht the holster was a creak o matic, thankfully I was at home, because I was creaking like our old hardwood floor and the wife made a comment asking why I always carry that thing around..
I may stop by a fabric shop and see if they have some sort of durable fabric that I can put on the holster. Is crossbreed the only IWB like this that squeaks? What are they doing differently, or is it the Horsehide that is the issue?
