At Fun and Gun, I was having problems with missfires, or so I thought. Came back from the TDI, cleaned my Glock 17 real good, like always. I was at the range today, and same thing. Missfires. LOTS of them. With different ammo.
Today was really cold. Fun and Gun was cold as well, but my gun stayed warm at Fun and Gun because it spent a lot of time in a holster. Today, it was sitting outside at the ~35F ambient temperature, so it was cold as well and just would. not. work. correctly.
My friend took it apart and promptly diagnosed the problem as a clogged firing pin channel. I got home and took the whole slide assembly apart. Removed the back plate, pulled the firing pin assembly and ejector, everything.
The firing pin assembly and channel were...shall we say....disgusting? Yeah.... it was really dirty with gunk. I went through 50+ q-tips getting that firing pin channel clean.
So, let's this be a lesson: DO NOT OVERLUBE GLOCKS!!!! The only things that need to be lubed on a clock is the rails. That's it. Do not attempt to lube the firing pin channel. That hole that's in the slide? IT IS NOT FOR LUBE!
