Glock firing pin channel removal and replacement

Removing and replacing the firing pin channel in your Glock pistol can be a bit of a chore (removing it is the hard part, putting it back in is fairly simple).  While it isn’t something that most Glock owners will never have to do, if you are refinishing the gun, it would be a good idea to remove the channel while you are blasting and coating the slide, and replace it when you are done.
