i just bought a tec 9 i oiled it well but it seems the slide does not come back all the way back when it fires.it will only shoot a round or two and then is jammed. is this a slide problem ,an ejector problem, or would using a plus p ammo do the trick? i currently use a 9mm luger 115 grains, it's all new ammo and i tried 2 types. thanksfor any help as i don't know alot about this gun.

  I would disassemble and inspect the gun to make sure there is no broken pieces or guides. I also suspect that you might want to check the chamber for heavy reaming grooves which will retard the blowback action or your gun. A little polishing or the liberal use of steel cased ammo will smooth out the grooves and improve cycling.

  mare sure the bolt isnt dragging on the feed lips of the magazine..If you have another mag try it and see what happens. Look at top of mag for any indication that bolt is hanging on it or dragging

  could be the mags, but could also be a factory screwup of where they positioned the magcatch in the frame. It might be necessary to remove metal from either the mag catch or the mags, letting them sit lower in the frame. If the mag catch is an available part, I'd start with it. Mags cost more, and you need several of them.

  Hey timinpa! Acyman is right about the mags. I had to remove metal from the area that the mags catch on the release in order to get them to even seat. When you say that the bolt does not come back all the way, does it go past the allen screw in the bolt? Here is where I'm going. I had to replace the extractor in my tec 9 and when I tried to re-install the bolt, the allen screw holding the extractor in was catching in the tube that the bolt rides in. It seems that the new extractor was slightly thicker than the old one. I had to remove some of the top of the allen screw to make it even with the bolt. Try some different kind of ammo too. It says in the manual that they are very ammo sensitive and I have definately found that to be true. It also says not to use +P+ ammo and I have found that it eat that up with very few problems. If all else fails then sell it. Mine works good now, but I have tired of it and I listed it on gunbroker just to see if someone wants it more than me.
