Your Browning is an excellent carry gun & it's in super nice condition.
Both Kydex and leather will eventually cause finish wear on the the rub spots of the firearm.
Kydex will wear a firearm finish quicker but crisper.
So if you have an investment grade firearm that you eventually will want to sell as absolutely "MINT" condition then naturally you would not want to carry that one holstered and would keep it regulated to constant "safe-queen" status.
That having been said there ARE some things that you can do to minimize the "wear" and preserve the finish on a firearm holstered in leather. (See Below)
> Keep the inside of your holster wiped clean with a cotton cloth.
> Do the plastic bag or the "Waxed Paper thing" which will prevent your leather holster from being overly tight.
Leave your firearm holstered that way for about two days.
That helps because it forces the molded leather to stretch and conform itself to any overly tight firearm high spots and edges.
> Keep a light protective coat of Renaissance Wax on your firearm. <~~~
This stuff is really super great. It is HARD -PH Neutral - Not slippery - and it provides great finish protection.
There is always some listed on Ebay.
> Do not repeatedly practice drawing and re-holstering with that particular firearm.
Holster wear on a carry firearm is not something that I fret about and I don't see any problem with honest holster wear on a carry gun.
I own a couple of "investment grade" guns and naturally I don't carry them at all since my original intention on buying them was to keep them absolutely "Mint" for maximum dollar resale value at some point down the road.
