Hi,
I detail stripped my gen 3 19 a few nights ago and noticed the channel liner slid out when I removed the firing pin assembly. I replaced the liner with a new one and noticed that liner also slid out when the firing pin assembly was removed. After going through four new channel liners, I'm not sure what to do. All of the liners in my other Glocks are a very tight fit, each requiring the Brownells tool to be threaded to remove them. This 19 however, the liner will slide out when shaken.
Any ideas?
