My Hi-point C9 in 9mm para has a peculiar jamming problem. Most of the time it functions just fine, but sometimes the extractor claw slips off the rim of the fired cartridge, and the empty case stays in the chamber until I drive it out with a rod. This makes it not viable as a self-defense weapon. Both factory and handloaded ammo pass the plunk test, and fall out on their own. When I close the slide on a cartridge, fired on unfired, it tends to stick at some point in the chamber, and will not come out by the extractor. I lightly polished the chamber, but am afraid to remove too much metal. It appears that this particular pistol has a tight chamber. I'm not sure I want to spend the money on a throating job, for a pistol that I have less than $100 invested in. Does anyone have thoughts or recommendations? Thanks.
