Very accurate article. Seen it first hand. I was shooting with a buddy about a month ago and all of a sudden a big burst of stuff came out the trigger area, blew the magazine out of the bottom and my buddy had black marks all over his hand as well as a sore hand. It was a glock 23 I believe. .40 sw was the caliber. The case looked like the ones in the article. The ammo was HSM factory reloads.
