I have owned and carried LW commanders for over 30 years now, I have yet to damage a feed ramp. Solution to a theoretical problem mostly.

People see the "wear" on the feed ramp and think it's wearing through the hardened part of the anodizing, when it's really just the color layer, the hardened layer is clear, so it's still there. Type 3 is harder than steel at 50 on the C scale.

I understand the theory, and I have even seen a couple of damaged feed ramps. I have tried to replicate the damage and I have been unable to replicate...those who are doing it, are truly over-achievers.
