dansedgli Posted June 28, 2014 Share Posted June 28, 2014 I've got a 9mm STI edge. Like clockwork, after about 150-180 rounds I'll have fail to extract issues. It will leave a spent case in the chamber and try to feed another live round. Once it starts to happen it happens every 2 or 3 rounds. If I take the top end off, wipe the rails down and re-oil the slide it will fix it. What I don't get is how this fixes the extraction issue. Wouldn't extractor tension be a separate issue altogether? Any ideas? I'd also like to get more rounds out of it before this problem starts. I'd have to clean it halfway through each day otherwise.

klee Posted June 28, 2014 Share Posted June 28, 2014 Recoil master or guide rod? If you are using guide rod, what # spring are you using. How is the extractor tension? Is the extractor tunnel dirty? AFTEC maybe your solution but you may want to check everything else 1st. Link to comment Share on other sites More sharing options...
toothguy Posted June 28, 2014 Share Posted June 28, 2014 You might try removing the extractor and cleaning the tunnel out with a Q- tip. Mine gets a black thick paste build up that interferes with the extractor tip. Link to comment Share on other sites More sharing options...
OperationHitFactor Posted June 28, 2014 Share Posted June 28, 2014 Give the extractor tunnel and extractor a good cleaning with Alcohol. Don't put any lube on the extractor or tunnel it will just gum things up. Try giving a little extra tension on the extractor. I have never had much luck with STI extractors. Personally, I like Aftec extractors, but plenty of guys have good luck with Wilson or Egw. Link to comment Share on other sites More sharing options...
bountyhunter Posted June 28, 2014 Share Posted June 28, 2014 (edited) Check extractor tension. Maybe the oil increases slide velocity enough to make it extract, but it still sounds like an extractor issue. The barrel throat may be a bit tight and need a light polish. I assume Wilson still sells the gauges used to measure extractor tension. You need to keep it at about 15 - 20 ounces. Inspect the extractor tip under a glass to make sure the hook is square and sharp. Dumb idea: make sure you have the 9mm/38S extractor which is different than the .40/.45 extractor.

dansedgli Posted June 28, 2014 Author Share Posted June 28, 2014 Thanks guys. I'll take it apart today and give it a good clean and add more tension. It's got a recoil master in it. Not sure if it's light or heavy but it feels much easier to rack the slide then my Trojan with a 14lb spring and flgr. Link to comment Share on other sites More sharing options...
klee Posted June 29, 2014 Share Posted June 29, 2014 9mm should be light. Link to comment Share on other sites More sharing options...
