I had issues with unloading and loading. after I did those mods I had no further problems
with snagging and hung up shells. I also had a problem with the cartridge stop. I had to really force the shell to
overcome the stop. I found that the angle at the end was not angled much at all and the end just was chopped
off and had a rather sharp end. so after looking at different pictures I filed a bit of angle to the end and cleaned
up the sharp end. now loading the shell requires very little effort beyond overcoming the spring. discussion here. http://www.mossbergowners.com/forum...stop-how-many-differant-ones-are-there.13260/
yer welcome. just ask if you need clarification. although non of my issues were serious, the mods just made it so much smoother to operate. just a heads up. do any mods in small steps. I didn't have to do as much as was pictured to make mine function properly.
