So i have a gen5 glock 26 with a round count somewhere around 8-9 thousand. I have had just a couple malfunctions with this pistol until last week when it seemed to loose the ability to extract a round. I detail cleaned the slide and put it back together, no improvement. So I replaced the extractor and extractor spring/ rod with a Suarez branded one, no improvement. During live fire it will send the slide to the rear without pulling the spent case from the chamber. This results in a double feed. When I chamber a round and pull the slide back by hand it will pull the case about halfway out of the chamber before the extractor claw simply slips off of the case. I don't notice any additional resistance as this happens. Any suggestions?
