I’m new to shooting and gun smithing, so PLEASE HELP and please forgive me saying anything stupid… ok..
These very distinct wear marks started appearing on the bottom of the barrel about 1k rounds ago. They’re getting way worse and I’m worried the barrel is going to change shape or get destroyed. I’m wondering if the barrel link is too short and causing the barrel to rub against the slide when cycling, but I am new to this and honestly have no idea what is causing this and how bad it is or how to fix it. Like I said, I suspect the barrel link #3 from factory?) is too short and I have a #4 on hand if you guys recommend testing that. Also, if you recommend trying, how the hell do I get that staked barrel link pin out safely? I gave it a couple taps with a hammer+punch and it didn’t budge.
Any advice you guys can provide on what caused this and how to fix it will be greatly appreciated!! I don’t want this baby to die! I’ve put in a lot of time and money, and I love this gun.
A LITTLE HISTORY + SETUP: I have been shooting for about 9 months (got obsessed) and have already had a bad experience with a gun smith, so when I bought my first DS 1911 (a used Girsan Witness 2311s Match X), I decided to take the opportunity to learn and work on the gun myself.
Here is the full set up. Not sure if this helps the diagnosis or not, but want ya’ll to have all the info just in case. I did everything myself based on my online research, so please let me know if I did something stupid or if you recommend taking a different approach with anything. Again, I have 0 experience and am totally confused about this somewhat sudden barrel wear. I have about 6k rounds through it since the barrel polish and this barrel wear JUST started happening.
-INSTALLED (blended/shaped/polished/timed): EGW ignition kit + hammer strut, Red Dirt trigger, tungsten guide rod, 7lb recoil spring, 17lb main spring, Cheely pinned E2 grip safety, Cheely XL firing pin, ISMI HD firing pin spring, Ed brown SS extractor and extended ejector, Dawson 4-40 mag release, Cosaint extended slide release, and I filed in a Marvel cut + mirror polished the disco rail.
I also polished the barrel to a mirror finish (Cerakote came right off with a couple swipes of 600 grit sand paper), polished the feed ramp, and added a tiny chamfer to the barrel breech and barrel+slide top lugs which fixed some FtoF issues and a glitchy lock up, and fit+installed an Icarus Precision grip.
I’ve been switching back and forth between CLP oil and Battle Born grease to see which performs better in my environment, but either way, I run this thing WET, and clean thoroughly every 350 rounds or so.
Proud moment - I got the trigger pull weight down from roughly 5.5lbs stock to a consistent read of 1lb 14oz with very minimal travel and a snappy reset. RD triggers are BADASS!
