I bought my m9 a1 a year ago from SFRC. It had 2/3 fte per mag. I contacted them and they told me Northsylva was importer and I should contact them for warranty issues, Jeff Chow @ Nsylva sent me out an new extractor, spring and beveled plunger. I also got the extractor kit from Steyr USA. All three extractors i now have are slightly different in shape, claw angle and width. From my trials and errors the north sylva extractor with the dome plunger and new extractor spring from usa combined with a wolf spring did the trick for me. Shoots great now. Join STEYR CLUB.com lots of good info there about fixing, cleaning and dissembling the M9 a1 . Brownells #969-000-125wb it is by WOLFF GUNSPRINGS mfr part number 26132 , a 3 pack of springs for 7.49. Stick this spring inside of the steyr spring and cut the access off flush or a hair longer. Then reinstall in gun with the dome plunger. Tip is to do the install in large zip lock bag because spring could fly off and get lost.
