Not sure where you got your info on glock finishes but all 5 of my gen 4 glocks finishes are holding up just like any other QPQ nitride process gun. The black oxide will wear off in some spots using kydex holsters and carried daily. But I kinda like the character it imparts.

Also you're OPINION of best gun finishes is a little subjective considering you don't give any parameters as to what you believe go into making the "best gun finish"

Maybe you should start a new thread on that one
