Inspect it carefully. Especially if you pick up "range" brass where Glocks are in use. This is typically going to be 9mm and 40 S&W. Most resize dies can't fix the case head ballooning. The die is adjusted to just contact the shell holder on the downstroke. A set of cartridge gauges is a very good investment in quality control and safety. I have them for every caliber that I load and for which one is available. I still need to purchase one for 45-70. A perfect fit in the cylinder of my Magnum Research BFR is my current final quality control step. I can check 5 at a time with the cylinder sitting on the bench.
