So some of you may have read my thread about my Ruger failing to extract about 1 or 2 out of 50 rounds. The spent case would be blown about halfway out of the chamber sitting on top of the mag with a fresh round stripped. It would eject with authority at the 4oclock position every single time, then bang out of nowhere complete failure. I did run a box of PMC through it with no problems, but I could only find 1 box to purchase. But it malfunctioned with Blazer Brass, PPU and Remington. I thought I had the problem worked out after the 50 flawless PMC it did 50 flawless Blazer Brass then first mag of the second Blazer box I had a failure. With no 9mm ammo in stock I was unable to run WWB or Federal through it. Ruger sent me a shipping label and the tech called me yesterday, "I just put 70 rounds of Black hills 9mm through it with zero problems. Damn. They were super cool, he said he would replace the extractor if I wished and I said yes. Should be back to me today or tomorrow. I am going to run it stock to see how it does and then drop in my Galloway 20lb spring and guide rod combo. I really like this gun so I hope it runs. I also wish I could find more PMC to run through it to see if that was the issue. Any opinions are welcome.
