Well, have a jam once. The manual o ams to clear it is more than you will be able to do under stress, no matter how much you train. My advice to one o my students who had one (when she asked ater a jam) was "Throw it at him. He wont have any better chance o clearing it than you did, less even, and run." As it turns out, she was in a deensive encounter. She shot the guy twice in the chest and threw the then jammed gun into his temple. THAT put him down, whereas a 480 through the heart and the lung did not. BTW, he recovered fully from the wounds. He was out o the hospital in less than a week. She went with a GLOCK 19 after that, and used a high quality defensive round.
