Not a lot to do after shooting on my range except clean the guns. I saw somewhere on YouTube someone polishing their shotgun bore using a drill, bore brush, 000 steel wool, and brasso. They never showed the after polishing result. I've polished the feeding ramps on my pistols and rifles using a dremel, felt polishing wheel, flitz polish, and a whole lot of patience....being careful not to change any part of the geometry. I thought to myself..why not put a shine on the 590a1? Here is the result. Form and function are still 100%. Stay safe!
