Hi All New here and this is my first real post. Recently got a C9 (my 1st pistol). Took it to the range a few times. All was well and good. After putting about 100 rounds through it,its starting to jam. Cartridge gets stuck on the ramp. Used two different cartridges, Blazer & Hornady. Anyway, I thought maybe it needs to be cleaned. Now the Hi Point manual is very vague on this! Is it cool to run a brush down the barrel from the muzzle side? I've searched and googled, but all I find is either a total tear-down, or "follow the manual." Any help from some of you more gun savvy folks out there?
