Picked up a new security 9 and am under 450 rds. Have some bur's forming below the rails where the barrel lug cams back. It's apparently smashing back and moving metal. On a steel frame i would worry less. With anodized aluminum i am worried. The way I understand if the color is missing the the hard coat is gone. Someone pls help determine if this is normal acceptable wear or damage!?! I know, I know I should have saved x amount more and bought x pistol. I have taken my share of ribbing for my cheap ugly pistol. I like it. I just hope it stands the test of time and isn't about to be rendered useless. I emailed ruger and haven't heard back yet. I'm sorry my first post is so long and do low i appreciate any and all help. Th and you for your time guy's.
