My .380 jammed on me once after me, my gf and brother had all taken turns shooting it pretty much non stop, about 70 rounds total. I took my Sub 2000 out last weekend and fired three 15 round clips and one 10 rounder as fast as I could load and shoot. I was basically seeing if it would jam, overheat, etc. No problems whatsoever, and when I cleaned it I was suprised at how little residue there was. I read a lot of different gun magazines and all of the reviews from different writers about Kel Tec, especially the Sub 2000 and SU-16 have been positive. I bought the Sub 2000 because it's pretty unique and I already have a pretty big gun collection so I though it would be a good addition. If I was going to war it would not be my weapon of choice, but for the money it's a good gun and a hell of a lot of fun to shoot.
