I’ve had probably 12 glocks through my collection. All of them had grip reduction, stipple, double under cut. All except my daily carry had slide window cuts, serrations, or optic cut. What was appealing most to me about the shadow systems was that it had all the features I would have done to a stock Glock anyway plus the optic mounting system is pretty cool to me.also could change the grip angle to more of a 1911 style. I think I’ll still get one soon though. And throw in a dk trigger I have laying around. I’ve just always been a Glock guy even though I’ve always had to put a lot of money into them to get them where I want them to be. But I’m the same with all my guns especially ARs
