I've got a 1187 special purpose that i use exclusively for turkey hunting. I shoot Remingtom 3" nitro mags out of it. This year it quick cycling it will shoot once and not feed the next shell and the action stays open as if it's empty. I've got a friend that works on guns and knows what he's doing most of the time. We swapped the trigger ***'y out with one from a Model 1100 and 1187 and it cycled at his house. I carried it turkey hunting shot it once and it still didn't cycle. We replaced the o-ring right off the bat, what do I need to look at now? Please help I'm getting desperate.
