I have had the same Kimber Stainless TLEII for 11 years. I have carried it a lot. Ive added an extended mag well and VZ grips, but its otherwise stock. I've always prefered blued finishes over blasted stainless but I bought this gun for utility. Oddly enough, the bead blasting shows no appreciable wear. Should I have it koted matte black or leave it as is? This gun has no rattle to it, leaving me to believe its pretty tight. Will koting it require the slide to be refitted to the frame? I've done rifles but none have tolerances this tight.
