Saw,
We have dozens of Glocks in the office, so far no one has seen that, or if they have no one has answered up. What we are seeing, are the night sights kind of rusting......guess they don't have the same coating the rest of the gun does.
Other issues we have seen are: Glock 22 frames cracking (Glock recall for them); Glock 27s jamming (we'll get there); Glock 22 slide breaking things and flying off ( :shock: freak occurrence per Glock and everyone else, never seen nor heard of that one before but guess it was a hoot to watch); couple Glocks blew up (think that was an ammo issue), and bad mags after a couple years use.
Laid over in Hawaii one time on my way to Guam, had my SIG 220 on me (cleaned, oiled, etc.). Got to Guam after essentially an entire day with 6-7 hours in Hawaii......the 220s slide was rusted!!!! Go figure.
