its done by hand. Laser stippling is pretty slippery and is nasty. really need a enclosed vented area for lasering polymers, nylons ect..... now anything metal like guns, revolvers, knives, ect.... i can do full engravings like old scrolling on 1911 & 2011's, snakeskin and snakes on revolvers, skull patterns, gucci and louis vuittn patterns on glocks..... you name it....
the stippling is real nice, like a denim style pattern, very grippy but doesnt kill your skin. the undercut that is done on them is real nice and gives you a bit of room for your middle knuckle.
