Wanted to show folks the process used to polish the feed ramp, in this case on a Beretta PX4 Storm. This method can be used on any pistol or rifle. The primary benefits I found are increased feeding reliability (was not an issue on this PX4) and noticeably less fouling during use. It also makes it a lot easier to clean with a cloth for a periodic wipe-down. Used a Dremel tool, felt polishing wheels, Flitz polish & some Alcohol
