    I took my FEG .45 to the range earlier this week. It was the first time I've had a chance to shoot it.

    Unfortunately, I got several 3-point jams, fairly difficult to clear. The jams happened at the third or fourth shot.

    The jams happened with:

    * both the original FEG mag and a new ProMag
    * both Blazer aluminum case and brass case (all FMJ RN)
    * the jammed rounds had a small but deep ding about 1/8" behind the case mouth

    A few shots weren't *quite* jams; the gun just didn't go all the way back into battery. Lightly tapping the slide forward got it to chamber the round. Well, except for once, when I made a 3-point jam even worse...

    The gun had been cleaned and lightly oiled before shooting. I checked to make sure the magazines were properly seated.

    After bringing the gun back home, I pulled the barrel and dropped a round in. It seems to fit the chamber about like my 1911 barrels.

    I field stripped the gun and looked at the feed path. It *looks* to be pretty good; the magazine presents the round high, and the barrel is ramped. There's an extension on the hood that fits into a recess in the slide; as best as I can tell, it's to help guide the round into the chamber, like the hood on a Saiga-12 barrel. I think, anyway.

    Here are some pictures:

    Here's the cartridge to barrel location with the barrel forward and back.

    And the face of the barrel, and a somewhat blurry shot of something unusual - the ejector lightly touches the back of the case. As far as I can tell it's supposed to be that way.

    I realize there probably aren't any FEG experts here, but I'm open to troubleshooting suggestions. Frankly, my initial idea was to just try some different ammo.

    Al that I can tell you about that gun is that FEG borrowed heavily from the old S&W autos (39/59 types), so yours is closest to the S&W 645. Info for troubleshooting those guns might be useful. Emphasis on might. I've never tried to adapt parts from an S&W to an FEG, so I don't know if that is possible. They are more like nearly identical first cousins that identical twins. Magazines might be easily adaptable and S&W mags are high quality. I've done that with other guns with good success.

    FEG's aren't high end pistols, but chamfer the feed ramp sides about half way up. Use a fine jeweller's file. NO ROTARY TOOLS.

    Dont know about a FEG. But the case head/rim must slide up the bolt face freely on feeding. The extractor, if to tight or not shaped correctly will slow the round on feeding from the magazine. The feed ramp makes the ding. Photo shows other problems. BoltFace.jpg

    I think my next step is to clean everything in the breech area with acetone and paint it with machinist's layout ink. Hopefully that'll show me where the cartridges are going when they're failing to follow the feed path.

    I also took this as an opportunity to buy some new toys, and ordered a couple of bullet molds for differently-shaped bullets. I'll load up a few magazines with different powders and bullets and see if it likes something else better before hauling out the Dremel and angle grinder...
