Hello having some problems with my cm-11 9 mm. (sillymeter)
The junk plastic mags don't feed well. I took the gun apart cleaned it all mag looks good but it's like it wants to feed 2 round some times and the gun won't allways cock the hammer. Geting so annoyed with it like the gun it's fun to play with as that's all it's really good for and shooting skeeters. Has any one had this happen to them if so how can I fix it and sending it in isn't an option. Was going to try the mags with the metal lips to see if that helps or get the ss insert lips from Cobray please help anyone

    Most of the time in my exp, it's the mag lips. I'd try some better mags.

    I remember seeing the first ones, semi auto, but they fired from an open bolt, then BATF had an epiphany and stopped any future production of semi auto firearms with an open bolt, those were lots of fun....

    The non cocking issue is usually ammo related, since it is blow back operated, and has a very heavy spring, the UZI had the same problem, and IMI Sampson +P ammo for the UZI worked very well.......

    That is why you consult the Manufacturer as to if you can use +P ammo in your gun before you do, as in the case of the UZI / IMI the ammo was specifically made to function the UZI and said so on the box.......

    My Masterpiece arms Mac-10 clone uses Sten mags which are cheap and metal, never a problem there.

    See if this fit, don't recall if I got mine here but seems to be a good deal:

    If this post is non welcomed, I can always give you a recipe for making "tostones".

    Cobray was bought out a good while ago, and the company making them now is in a different state. They were originally made in Ducktown, TN and are now in Bismarck, ND.
    The original Cobray M-9 had a very strong recoil spring; took full power ammunition to cycle the action.
    The double feeding is probably being caused by either wear on the feed lips of the magazine, or the feed lips are spread out enough to present two case heads for the bolt.

    The 'problem' of which you speak is common with that pistol. If you feel comfortable field stripping it, a good bolt cleaning is probably in order. Pay particular attention to firing pin and firing pin channel. Also check firing pin and channel for burrs. Check firing pin is free to move in it's channel, and is not binding or sticking in same. Check trigger and sear are moving freely and fully resetting with no binding.

    If you do field strip it, pull the pins while the thing is in a BIG plastic bag. Under best conditions, parts can launch for incredible distances.

    When I had my 01 license, I sold quite a few of the old models. They are twitchy, and prone to malfunction in the manner you are experiencing if enough dirt and 'stuff' accumulates in the right areas. The binding/dragging/failure to fully reset of the parts I described above is another cause of that particular malady.
