Pistol jams

What would be your thoughts on a jam like this? It is a Star 30 M.
im thinking extractor or magazine? I’ve used several types of ammo.As soon as I hit the mag release it closes up.

    Is that a spent shell that did not eject?  If so probably a weak extractor spring.

    Id measure the ammo for SAAMI cartridge drawing  spec comparison.

    Inspect the magazine closely for defects. Can you hand feed unfired rounds through the gun? Use muzzle control caution.

    Check a pistol schematic to see if a small coil spring contols extractor tension. That's an easy repacement.

    Check the jamed case for defects that might be caused by chamber irregularities.

    If that is a live round in the chamber then you have issues. I had a Ruger 1911 that when the slide would come back over the top round in the magazine it would “pop” it out of the mag into the chamber. Then the slide would pick up another round out of the mag and try feeding that round too. Ultimately Ruger replaced the gun. A gunsmith friend said the frame geometry was wrong and slightly out of spec.... all this to say if it’s a live round you got issues. If it’s a spent case, get new springs all the way around, extractor, recoil and finding pin. 
    Aim higher, or get a bigger gun.

    What he said.

    Wait-if it were an empty chamber, then it would probably be your thumb hitting the slide release and locking it back in recoil.  

    But is that a loaded round half in the chamber?

    Not a loaded round.  It is spent.   Thanks for the input, a little more to work on I guess.  Sometimes it'll shoot 10-15 in a row with out jamming.  The jams always occur in first few shots.

    Start with the extractor & spring.  The 1911 check is to clip a live round under your extractor hook & see how hard it is to shake it loose.

    Also check the inside of your chamber for crud or pits.  Less likely an issue than extractor grip, but it is part of the puzzle.

    Yeah, what he said.  Also make sure your breech face is clean and smooth and clean really well under the extractor claw.  Sometimes carbon hardens in there.

    This. I have had exactly two instances of extractor problems, and both were due to crud under the extractor.

    They're a hard spot to clean.

    I'd start by cleaning really well where the cartridge sits. Looks to me as though there is a lot of  carbon build up and maybe stressed fractured metal there.

    I have steel dental pics that I buy on Amazon or eBay and they make short work of hard carbon fouling in tight places.

    Regarding removing crud/carbon fouling from those hard to reach places. Science&Surplus and Amazon sell cheap Chinese dental pick instruments made of stainless steel for cheap. Works on pistols, rifles, and shotguns in those hard to reach places. Think outside the box. :)

    Sounds like two different problems.
    The extractor failing to extract does seem like a crud or spring tension problem somewhere.
    The slide closing when you press the mag release seems like a different problem.
    I'm not familiar with the Star 30M. How does it slide lock?
    (Star 30M)

    I'm guessing it goes to slide lock like a 1911. Take the mag out and lock it back manually. If it stays back fine, if not, check the slide lock notch for rounded edges. It may be that it needs the help of the mag spring tension to keep it locked back.
    Without pictures of the possible problem areas, we can only guess.

    Actually the slide closing when you hit the slide release is normal for this failure.  You have a failure to eject and the next round in the mag can get out so it jams between the breech and the rim of the spent case that is still in there.  When you hit the mag release that takes the live round out of the way so the slide slams on to the empty unejected case.

    Sounds reasonable, I wasn't too sure I was reading the OP right. Thx.

    It’s really tough to visualize the whole thing by just looking at a photo and trying to visualize everything that is going on in the pistol.
