Fine Tuning Your C9

  1. christophereger
    Have you had a Hi-Point C9 come into your life and aggravate you to no end? Well the problem may be as simple as a few five minute fixes away to turn that buggy pistol into a reliable shooter.

    Of course if you get a new (or new to you) C9, clean it, lube it, and test shoot it first before you begin any of the below activities. Only attempt the following if you are running into failure to feeds and other jams.

    Magazines

    The magazines on these pistols have a well-documented tendency to nose-dive, where the rounds take a header downward, and stay that way. If you see this and the pistol itself doesn't automatically correct this when in battery (which means if it fires like this it's fine, if it doesn't, then you have a problem) take a look at the lips. A little gentle tweaking on the feed lips of these magazines with a pair of needle-nosed pliers is the best-documented tip for this problem. If you have a caliper, the openings for the feed lips should be they should be set at .355" to .365" with the optimum at .360".

    Remember the 15-round aftermarket mags and the carbine mags for the 995 are not interchangeable for the C9 so don't waste your money on those. More radical fixes if should this not work include filing down the hold-open bar inside the pistol itself (well covered in our forum )

    The ammo

    Many C9 users report poor luck with Winchester white box ammo and better with Federal, Hornaday, and Remington variants. Hi-Point/MKS tests their pistols before they leave the factory with a mix of several different loads although most rounds cycled through in Ohio are your 'cheaper' Wolf and Tula steel cased and poly-performance cased ammunition.

    Feedramps

    (thats a whole lot of polish on that feedramp...hope its not too much taken off!)

    The feedramps of the C9 are painted with a thick coat of protective paint, which will wear away rapidly after a few boxes of rounds. However many C9 end-users find that this coat is just a little too thick and contributes to the rounds sticking and not chambering properly. This can be fixed with a very slight application of a cleaner like Ballistol or a touch of very light (think 600-grit) sandpaper. Be extremely careful when doing this as you don't take off too much of the ramp and change the angle that the rounds feed at all together. Best bet is to take a little off, shoot the gun and check for improvements, then take a little more off if needed. Remember, while the chamber and barrel of the C9 is made of ordnance grade steel, the feedramp is Zamak-3 zinc polymer and very soft in comparison. Do not find this out the hard way.

    Guntorture tests has an excellent 13-minute video up on You Tube in which Rich walks you through step by step in the process of tuning the feed lips on your magazines and polishing the feed ramp on your Hi-Point pistol. In the video, he shows how Hi-Point paints the feedramp of OE guns with high temperature paint, causing the issue of the round nose-diving and failing to feed. Simply polishing this away with sandpaper or emery paper and not a dremel tool, will provide a much smoother surface for the rounds to feed reliably into the chamber. Using a pair of pliers or a multi-tool, he shows you how to modify the magazine floor plate and spring in about four seconds.

    Remember, Hi-point has a lifetime warranty and is one of the most responsive in the business, so take them up on it if you are having major problems that a little of the above doesn't fix.
