We are talking about a $400 firearm that will be carried everyday. We're not talking heirloom collector type guns. Holster wear from EDC is unavoidable. Who cares about the finish as long as the gun is accurate and reliable. If you're worried about resale value, putting a $250 aftermarket paintjob on a $400 gun will do much more to reduce it's value than to enhance it.
Can only add to what shootniron posted. Its a tool. Like my Glocks, who cares if it gets beat up? I don't carry heirloom quality guns.
