I purchased this nice looking semi a few years ago when I knew nothing about guns. The gentleman i purchased it from said it worked great without any issues. So...... I had a good look at it cleaned the barrels it came with and took it out. First shot was great but I couldn't Take another because it was jammed. I tried light loads to buckshot to slugs and or still wouldn't cycle the 2nd shell. When I turned the gun over I tired looking looking for anything obvious but the only thing odd was a tiny bit of epoxy on the one side of the receiver, along with what looks to be some filing of the metal. I am no gunsmith but am very mechanically inclined with tools too boot. From my perspective it looks like the spring on the shell lifter is weak and not lifting the shell high/hard enough. Either way if someone wouldn't mind throwing their 2 cents worth in that would be great..and thanks.
