I've wanted an 870 for a while, and finally pulled the trigger on a Synthetic Express Super Mag at an auction. Once I got it home I broke it down and cleaned it (which it really needed) and put it back together. I couldn't get it to pump after the basic cleaning, broke it down again and cleaned the trigger assembly and I can tell what the problem is, but not how to fix it. The release button for the pump gets stuck in after doing a dry fire and you can't rack it. So, does anyone have any thoughts on what to try next? Clean and oil it again? I'm at my wits end, especially since I don't have the internal knowledge on these. I suppose it's time to learn. Any thoughts on the situation would be greatly appreciated.
