How the phases differ
A phase is a separate version of the finish with its own colour scheme. The paint covers the slide, while the frame stays plain grey. Emerald turns the slide deep green with darker veins. We don't rank phases against each other; pick the one whose colours you like.
Wear on a Doppler-style finish
This is the detail that sets the Glock apart. Doppler knives stop at 0.08, so they are only Factory New or Minimal Wear. The Glock's range is 0–0.50, so it can even be Battle‑Scarred, between 0.45 and 0.50. On a Battle‑Scarred copy the marbled paint on the slide loses its gloss and breaks up into darker patches. Factory New keeps the candy shine.
