Has anyone had any problems with their factory plastic guide rods? I got my first Glock about 4 years ago, have added 2 more since then, and haven't had any issues personally; then again, my round counts are measured in several hundreds- not several thousands. I don't see it necessary to switch to stainless steel or tungsten to control muzzle flip or reduce felt recoil as advertised but if the plastic rod will end up failing as my round counts start getting into thousands, I may as well upgrade before it fails. Do these plastic factory guide rods hold up? Wanna kill these ads? We can help!
