I have been having problems with my 4" XD-9 extracting. I had a box of Winchester white box 115 grain and about every other one would not extract the brass and jam up. I have heard of using other ammo but i think it should be about to use any ammo i put in there. I heard lubing and under-lubing might help. My last resort before switching out the extractor is that i heard you can have extraction problems if you have limp wrists. Can anyone explain this to me please.
