I saw an ad in the March Guns & Ammo for an attachment for the Lee FCD that pushes the brass through the die to resize the bulge from unsupported cases in the Glock type chambers. Retail is 19.98, but I don't find it in Lee's online catalog. I don't own such a pistol but do encounter some of the brass. Looks as if it may be a way to salvage such brass. Appears to be an alignment sleeve and a long push rod. Also has the bullet sizer type of plastic container to catch and hold the sized cases.
