In the dog days I don't use leather holsters at all any more. I don't like what the moisture does to the leather - OR what the dye leaching from the leather can do to my clothes.
Missouri gets hot AND humid - so after years of trial and error I've decided it's stainless all the way for me. I'll carry either the Seecamp DA Detonics .45 with a clipdraw - or the SWT Speed-Six .44 Spl in a Desantis nylon IWB (as well as the Seecamp .32 in an Uncle Mike's pocket holster, of course). I've had all three literally dripping with sweat - but after many years have yet to encounter any corrosion problems.
Religious use of CLP hasn't hurt any either.
