Hi, still new to this forum. I got a new Glock 21 Gen 4 a couple of days ago and wanted to ask if you could help me. It's a great gun and I love shooting it but it spits brass all over me. Hot brass raining over you gets tiring after a while. Is this just because the gun is still new, shot 300 rounds today, or is there something wrong with it? The date on the spent casing is Apr 2012. Thanks for your input.
