to make a short story long i was skeet shooting with my 590.it was fun,have never done that before.well after about 20 trap load rnds i have a hull that has failed to be extracted.lucky i have my leatherman.i cleared the spent hull then i noticed the extractor was sitting high out of the bolt and the extractor spring had worked itself out from under the extractor claw.the gun is and was extremely clean and there was no crud accmulated around the bolt or chamber .the gun is now at a gunsmith with instructions to fix. has anyone had this problem before,
