Hey all- I was detail stripping my New Kimber Custom II, and found my plunger tube was loose. Called Kimber and have a new plunger tube assembly coming free of charge. Upon further research I guess Kimbers are notorious for loose plunger tubes. I called a local gunsmith to have it installed; and he proceeded to say, "what the hell is a plunger tube?". So it looks like im going to have to tackle this one myself. The YouTube Vids doesn't make it look to hard with the right tool, which I will be purchasing. My Kimber has 455 rounds thru it so far with only one malfunction. As I'm still learning all about the platform, what problems can occur with a loose plunger tube? Wanna kill these ads? We can help!
