Im thinking about mounting a Surefire X300 on a Gen 3 G22 which I believe was manufactured in early 2010. However, Ive heard that weapon lights can cause the G22 to have reliability issues. Has anyone personally experienced or witnessed this? Also, I noticed that the X300 has a couple different mounts to choose from, so maybe only one of those types of mounts was causing problems for other people. Im really hoping that either Glock addressed the issue on my year 2010 G22, or that Surefire figured out a solution. Id never put anything on a Glock that would compromise its supreme reliability.
