well, i have 4 dies for my .380, but i honestly do not remember if i bought it that way, or if i bought the fcd separately. i will tell you this, i have fcd's for almost every die set i own. but very seldom use them on pistol rounds. the only real advantage to using the fcd in a pistol round is the brass can be all different lengths, and still get a good crimp. the only other thing i will do for you is make sure every cartridge will chamber, as it makes certain they are all small enough around to fit into a chamber. if your bullets are all the correct size (think an over sized cast bullet), and there are no other loading problems. you really do not need one. if i was going to hunt something that may eat me, it would be a comforting thought. but for anything else, not necessary.
