Okay, first off, as a lawyer, I'm disappointed in the overwhelming lack of lawyer jokes here. Not that this is a joking situation, but a lawyer involved in an unintentional discharge seems like the set up for a joke. And, while some of the more sensitive would see the situation as not warranting a joke, the fact that she suffered minor injuries and will be fine makes me think that she's taking some light-hearted abuse in her own life, and would forgive us a laugh with her (not at her).
Second, I feel I must agree with the many postings that say Glocks are not the best choice for an inexperienced gunner. That said, in my part of the world, three agencies issue Glock .40's (22, 23, and 27), and I can think of five unintentional discarges. One was an officer drawing from an ankle holster during qualifying, who shot himself in the leg by pulling the trigger when the slide caught on his cuff and brought the gun to a quick halt while his finger was on the trigger. The second was on the same day, when a second officer went to assist the first. He put his own Glock 27 in his case, secured the case, and assisted in first aid. When he got home and ready to clean, he dropped the empty mag and pulled the trigger to strip the gun. You can guess, a round in the chamber, and a hole in his hand. the third is much like the second. Glock 23, fell asleep after cleaning, awakened by crying baby. Took care of baby, realized he didn't clean his gun (lack-of-sleep induced thinking), so he drops the mag, pulls the trigger, and puts a round in his calf. Fourth was a senior detective who decided to clean his Glock 30. Did so properly, then loaded the chamber and dropped the mad to top off. Phone rang, and after call, he picks up the Glock with no mag, aims at the closet, and pulls the trigger. Hydrashok into Nike, with predictable results. Fifth, and actually the most serious, an officer fighting with a subject. Subject makes a grab for the gun. Officer draws. During the struggle, officer jerks the Glock 22 back, and pulls the trigger in the process, one hit to the abdomen o fthe subject, who recovered later.
See a trend? Of the five I know of, four were purely operator error. The only gun-fault unintentional discharge I've ever heard of was with a Ruger P94, which as a result of home gunsmithing had the firing pin block removed, and the gun fired when the officer used his guh-side hip to try to force open a locked door.
If the shooter takes proper care, uses proper equipment, and pays attention to what he or she is doing, the Glock is no more or less dangerous than any other firearm. (By the way, no female officer has ever had an unintentional discharge around here. Hmmm.)
As for Glock .40 kB, none any of the firearms instructors are aware of. THough there was an interesting story with a Tec-9...
