I just bought my first handgun ever, and it happens to be the great C9! I took out to the range by my house and fired its first 150 rounds through it! I had about 5 or 6 jams with the first 100 rounds. These also happened to be winchester white box. I then purchased some Fiocci (spelling?) ammo at 10 bucks and it had no problems at all. I'm not sure if it was because I had already fired 100 rounds or because the Fiocci worked better. Anyway I had a damn good time and I'm happy to have purchased this gun. I think after 5 or 6 months of having the C9, I'll probably graduate to the 45. I'm already addicted!
