There are several ways to fix brass with the "Glock bulge". After seeing a video on one way, I decided to try it. It uses a Lee factory crimp die with the innards removed and a push rod to push the brass through, thus resizing it and removing the bulge. Here is the video:

Redding makes a die kit just for doing this. Last I looked it cost around $50. If you already have a Lee fcd, (or they can be had for around $15), all you need is the push rod. I work in a machine shop, and made one for myself. I figured while I was at it, I would make a few extras. I made mine out of 6061 aluminum and sized just smaller in diameter than the case, with a nipple that sets in the primer hole. (So cases need to be deprimed, or the nipple could be filed off). They are 2 1/4" long overall and will push the case all the way through the die so you can grab it at the top.
I am not trying to get rich off of these, just to pass them along to anyone who would like to fix their brass easily and at low cost. I have 14 available.
I will sell for $8 shipped in continental us via usps. Please respond via this forum with "I'll take one" and an email or pm.
