i use a KSC metal slide kit for my USP.45 when i skirm with it. yeah the trades are etched on, and i just basically engraved them myself using a small flathead screwdriver. going over each word a few times gets you a nice deep engraving and it looks a hella lot nicer than before. I find that the painted/etched on crap tends to go yellow/brown after wear.
