Paging @Tom_Jones ... I saw an email earlier this week that ETS is selling red colored mags. Not tempting enough, but then I got today's email. They are selling them in P-F colors!

While I'm normally not a fan of safety colored accessories for live weapons, if you want to be able to find your mags easily after dropping them, identify them among others during a class or match, or just have an itch to scratch.... enjoy!
The website only shows the 31rd Mags in orange, but maybe they'll expand that later?
