Had an odd malfunction of that 17B today. I was out "dog training" with my father-in-law and a few chuckers when it failed to cycle after firing at a departing bird. He emptied the remaining live rounds from magazine first and then, after trying everything else, he pulled the trigger on the spent shell. The firing pin dropped on the empty shell (again!) and it opened and ejected. I believe I have the option of returning it to the folks I bought it from or fixing it. Any ideas or suggestions?
