I've always hated the little holes and weird triangular patterns all over the front sides and top of the Glock 18C in this game, and now I am happy to say they are finally GONE! Nothing but smooth, smooth metal in its place.
A huge thank you to pawcio1337 for helping me get this mod finished after I've had it sitting on an SSD for 10+ months because I couldn't figure out what I was doing wrong with Unreal Engine.
