Now that I am learning more and more about my 642 w/ I.L., and hating it more and more everyday, what is the best material to get when looking for a new holster? Yes it has the aluminum " Airweight " frame with the anodizing that I fear will deteriorate with the wrong material holster. I live in hot and humid Florida to help with your answers. Is it correct that leather is NOT the way to go? For clarification, I mean a I.W.B. or S.O.B. holster. Thanks again everyone for the help, I took the advice on the new grips and immeadiately made a purchase. 26
