ive noticed a problem with the ammo i reloaded for my 9mm. it works fine but if i get a round in the chamber and i dont want to fire it the extractor wont pull it out. but when i fire it, it jumps out like normal. im pretty sure that factory rounds dont do that. im using a smith and wesson model 39-2 serial #A1256xx i think i read somewhere that the earlyier models had picky extractors. also im using once fired brass from midway along with some that i had fired throught this gun also, same problem.
