Ive had well over 1K rounds through my sw99, not a single jamb.. but I also keep her clean/oiled and only use quality ammo.
Krystle, go to the next Tampa gun show.. check out the kel tec's, great price, plenty of fire power and tiny! would fit in your pocket no problem. plenty of other firearms out there around the same size... just bring your jacket and see what fits in the pocket, lol. could always rock a shoulder holster under your jacket..
