I bought a brand new Glock 19 two weeks ago. I cleaned it per the manual and have fired it twice since then, cleaning it after each firing. The different metal parts on the frame and part of the slide have turned a brownish color. I have tried to get it back to the stainless steel color through cleaning but it stays this brownish color. I'll attach some photos. Does anyone know why a brand new Glock would look like this so...
