Frequently Asked Questions

Can I use a Dremel to polish my entire firearm?

While a Dremel can be useful for polishing small, specific areas like a pistol barrel, it's generally not recommended for larger surfaces on semi-automatic pistols. The Dremel can leave visible swirl marks that detract from the finish and make the firearm look less practical.

How do I polish the feed ramp on my Kahr MK40?

When the barrel is removed for polishing, it's an opportune time to polish the feed ramp. Use a Dremel with a polishing attachment and a suitable polish like Mother's Mag Polish to carefully buff the feed ramp until it achieves a smooth, shiny surface.

What's the best way to remove black residue after polishing a gun barrel?

If you encounter stubborn black residue on the steel after polishing, simply wash the barrel with soap and warm water. Dawn dish soap is particularly effective at removing this type of residue and restoring the clean metal finish.

Is polishing a semi-automatic pistol barrel a good idea?

Polishing a semi-automatic pistol barrel can add a 'bling' factor and a classy aesthetic, especially to visible parts. While a full high-polish finish is often seen as impractical for autos, targeted polishing of the barrel can enhance its appearance without making it look like a 'barbecue gun'.
