If you polish it it is more succeptible to rust if not maintained, yes. I wouldn’t do it. The gun is a duty weapon, meant for some serious abuse. I Had wear marks after first few mags but nothing changed drastically 12000 rounds later. Yes over 12000, I shoot a lot and I don’t have to pay for ammo .Great forum
Tell me , if i polish barrel , will it rust?
The dimple is a harness test done at factory. It's on many many firearm parts. Many many firearm companies do this to verify for proper metallurgy.and tell me , this spot , dimple as you said , do you want to say that every XDM has that dimple or just mine?
The Melonite finish used by Springfield Armory is a type of ferritic nitrocarburizing - it is, for lack of better words, "impregnated" into the metal itself, and part of its main job is as rust prevention.Tell me , if i polish barrel , will it rust?
As others have noted already, yes, that is completely normal, and yes, it shows up very rapidly as you start to cycle the gun's slide (either with actual live-fire use or from simply manipulating the slide).And I will send pictures of barrel wear , just so that you can see is that normal to?
