I'm having a heck of a time keeping my 9L running without an ftf. It looks to me like the sharp lower edges of the (factory) extractor are biting into the cartridge rim and/or relief and keeping the cartridge about halfway into battery. A couple palm taps on the rear of the slide will usually rectify the problem (sometimes more is required!)but it hurts when it happens 3-4 times in a stage...it's a game ender. I jumped out of CDP with a custom STI to SSP with a 9L with an Apex trigger (btw, anyone who competes with M&P's knows how sweet the Apex package is!) and am enjoying the gun and the caliber after years of refusing to give up the 4-5!
Anyway, am I on the right track with identifying this particular feed problem? I'm thinking of "melting" all lower edges of the extractor hook and any edge that may come into contact with the case, rim or otherwise.
Thanks, in advance for any assistance!
