I got to thinking, as the Gen4s come out and the Gen 2s getting cheaper, I was wondering if anyone did anything custom? I found some fairly cheap gen2 19 police trade-in's that might be worth me picking up one to try milling or lightening the slide, Duracoat or Cerakote, and grip stippling. I am just daydreaming, but it's kind of like finding an old rusty car, just gotta fix it up and make it better. Any thoughts? Pictures? Opinions?
