Did you check out the post from 9mm lover about 3-4 below yours ("Common problems")...The springs have lot to do with extraction..along with how clean the gun is...if you posted this info b4 , I appoligize for not seeing it. I've got Dons rod and a#22 spring and have shot 1000's of rounds now without extraction problems. also with my EFK barrell. UI do clean my guns and lube them well after every practice.
Hope this helps
