I tried to post this before if it shows somewhere else I am sorry. Any how being new to kimbers I have wondered about the wear of the aluminum feed ramp on my. Is there any documented round count on this?
Just had exactly the same concern on my Tactical Custom II. Ended up breaking down and calling Kimber.
The customer service folks were super nice. According to them some initial wear is expected but then it pretty much levels out around 500 rounds. They told me to use American Eagle FMJ for target practice and Federal 230 HydroShok for defense.
They said that those two bullets shouldn't cause any undo wear and that if I ever had ANY excessive wear problems that they would take care of it -- regardless of age -- as long as I used those.
They also recommended that I keep a round count book of how many and what types of ammo I've shot since most 1911 maintenance is tied directly to specific round counts (1000, 5000, etc.).
After speaking with them I pretty much realized that I was worrying myself over something that I didn't need too.
They said that the ONLY aluminum framed guns that they had EVER received back for excessive wear issues were those where the owner went 'polish happy' on the feedramp or that used really rough ammo (ie. Golden Sabre, etc.) That's why they specifically test with American Eagle and HydroShock.
