The coating flaking off the safety plunger is something that has been "a thing" on Glocks for over a decade. Some plungers have the coating, some don't. Glock probably contracts out a ton of their small parts, and there are variances from production run to production run. Thing is, anything coated will wear, if it is one of the Teflon finishes it could wear/delaminate very fast. Just from your dry firing. The Glock is a sub $500 USD pistol, just because we get ass####ed by a ####ty economy, taxes and markup here and people pay $800-1000 CAD for a Glock doesn't mean it's worth that much. That flaking will have zero affect on the function of your pistol. They are designed as working guns, not show pieces. Once you start using it, you will have way more wear, but even then, they hold up remarkably well, i haven't been able to shoot one out yet, and i beat the crap out of mine, though im not as hard on them as Ganderite, i clean mine every odd numbered year.
