Hey guys I bought a Glock 20C that begins with E on the serial number. I read they had problems with some of the rails breaking off on some of these runs. I was unaware of it when I purchased it. The gun itself is in excellent shape but while detail cleaning it with froglube I noticed not on the rear rails but the front 2 rails have small cracks in them one side worse than the other. The one pictured is the left side and if you look closely you can see the crack. I am worried that this will eventually break off especially firing the 10mm. Is it something to worry about or do all models get these cracks eventualy from normal wear, any input is appreciated.
