FNX-9 Extraction Errors? (resulting in double-load jam)
I have a new FNX-9 which I have owned about 1 month now.
I ran through about 300 rounds, mostly FMJ and two varieties of HP.
First 250 rounds were perfect....very accurate pistol...love to shoot it!
But started having extraction problems. I have been keeping it clean and lubed. The casing from the fired round won't extract all the way and the next bullet attempts to load, casusing a double-load jam. The extraction finger looks fine and is clean.
Took it back to dealer for them to test, but is anyone else having this problem?
Using American Eagle and Remington UMC ammo and Winchester Ranger HP and Federal HST +P ammo.
Anyone else having problems with particular ammo?
Probably Ammo or Dirty Chamber or Weak Extractor
I have a good grip and straight arm when I shoot. I went through at least four boxes and at least two brands of each FMJ and HP with no problems whatsoever. I was using a box of Remington UMC when I started seeing the problem. But then when I went back to American Eagle and Speer, they started jamming too. Thanks for suggesting a burr, but No, casings are clean...don't think its a burr. The dealer didn't think the extractor was weak, but that is still possible.
I am leaning towards a chamber issue, either insufficient cleaning, being gummed up at the edge of the barrel, or something like that.
But let me ask one other question: I use a small amount of gun grease on the slide where it rides on the frame. Could that cause it? (It worked fine for the previous 100 rounds)
