I love to capture the ejected casing in these kinds of shots. This is Jeffrey shooting a Sig P228 (9mm) yesterday. Yeah. His grip is squirrelly. I know. Hey, he's 15. He does what he wants.
I may as well give you a video, too. But in this video he's shooting an RIA (Rock Island Armory) .45 auto (1911a1 CS GI). See the picture below the video.
