A true gun nut will tell you I'm not right, but for all practical purposes this answer will do. You can always Google it and get reams of information to shift through,

Your right. I hand reload, and you can buy dies that will neck down a .40 to .357sig. .357sig is a screaming round by the way. I owned a compact usp45 at one time, very well built gun even better built than a glock. This coming from a glock fanboy too.
