    I have a iver johnson pony that wont extract fired rounds. I have changed the extractor and polished the chamber and am still having the same issue. Any input on what else it maybe?

    Yes it will extract rounds done manually and the gun has the 11b style extractor thats on the parts list on numrich. Does that extractor need a spring.

    Failure to Extract is kind of unusual. The only time I experienced that with any gun was with Wolff ammo where the laquer they coated the rounds with flaked off in the chamber so that on the third shot everything just stuck together. Are you sure you don't mean failure to Eject?

    If the 11b, it should not (part of the extractor acts like a spring).

    Have you tried to shoot it "gangsta" style (with ejection port up)?

    Will it load empties? How do they extract?

    Are you using "steel cased" ammo? As stated above, they could cause extraction / ejection problems.

    I'm highly doubtful that your extractor is the problem.

    I don't think the action is opening all the way. I think the extractor is working fine. It is pulling the shell out but putting it back again as it is not opening far enough to hit the ejector. When it doesn't extract is the hammer recocked? If the hammer is down I'm right. If the hammer is cocked I'm wrong.

    Im pretty sure its something with the extractor or chamber. The slide does go all the way back the the round stays half way in the chamber on stuck on the breech face half way ejected

    For what it's worth I have one of these and it does the exact same thing. I've broken it down several times, oiled it each time, but every other magazine load almost always stovepipes o e or two. Shooting brass from several manufactures doesn't seem to make a difference. Slide is smooth and springs feel good. I asked my dad about it(original owner) and he said it did this from day one. As it was a gift for my mom who prefers a revolver it was left as-is for several years. When it works it is fun to shoot and like like to get it fixed up for my girlfriend. If you come across a solution I'd love to hear about it!

    polish the hell out of the chamber. do fired cases have bulges or marks on their sides, or gouges on the rims?

    Thanks for the response. I've never noticed any markings on the cases. I'm taking it to the range this weekend and will pay closer attention. After my original post I took another look at it and the chamber/feeder don't look very smooth at all. I think you might be onto something with the polishing suggestion. I'll post my findings next week after I've put a few dozen rounds through it.

    Hi guys! Sorry its been a while since my last post. Haven't made it to the range yet. Didn't realize I was out of ammo and damn those rounds are hard to find these days. Finally found some on gunbot.net that was "reasonable". Unfortunately made in Mexico... But at this point I suppose I have to take what I can get.

    Quick update: July 4th I planned to take this thing out and see how it was running. However, the night before I broke it down pretty far to inspect and clean. Unfortunately I went a little bit beyond my abilities. Now I have a bent sear pin and some pretty scary hammer follow. At this point I am planning to take it in for professional repair.
