I had a few concerns over using kydex, and want my finish to last as long as possible. I have an MTAC, and like how it works, and don't want to switch to all leather. Is there anything a guy could do to make the kydex less harsh? Or are there some really good IWB holsters with high retention that do not use kydex? If not, then what is the best way to care for the NP3+ finish? It is my EDC pistol.
