Anyone ever have there pistols engraved? Have seen a lot that were already done, but haven't heard of anyone doung this after they've purchased their guns. Thinking about it almost like a pistol tattoo. Could be traditional or something custom to match ones personality. I've got a HK USP that has (name slips)... some kind of finish,, wondering if I could find someone to engrave it, would it have any adverse affects? Like scrathing through the paint on your car to the metal isn't good, rust is almost guaranteed. Anyone have experience with engraving, tips??
