What do you want engraving, and do you actually want laser or proper deep engraving ? Timpsons ( the shoe and key place) laser engraved the Glock logo on my G18 for me a few years back. But I generally have proper deep engraving on my rifs, L119's Hi Power etc. For that I use LC's engineering, but Jim has an epic waiting list, will be about a year for getting my latest GBBR L119 A2 trades and machining done !
