Note from the weekend,
One of the students picked up a Gen 4 Glock Thursday, and brought it to class.
I usually do not recommend bringing a new gun to class, but anyway, it was the only one he brought, and it was having problems from the get go, early in the day he( the student) being a Glock Armorer decided to diassemble the pistol, and a few smaller parts lauched themselves into the unknown, the extractor had to be forced out of the slide, and the Glock went home in a bag.
He finished the day with my Pro Series Smith M&P
Hope for Glock it was just a fluke
