From what I gather he has a pgo 870 with tacstar shell holder. owned it about 10 years, never had a problem. ast weekend, he said the action started "sticking/getting stiff", and he says its onyl doing it with a full tube and chambered round. I'm guessing the shell holder may need to be loosened or the mag tube and receiver need to be deepcleaned. any ideas? I can't see the forend being the issue because he said it's worked fine for 10 yrs.

Remove the shell holder and see what happens.

Loosen or remove the shell holder.

Scrub the chamber.

Field strip the gun and clean and lube everything.
If it has a shell holder on it, likely it hasn't been cleaned or lubed in a long time.
For some reason, people seem to think pump shotguns need no maintenance.

I agree. I told him to basically strip, clean and reassemble. If it's still having issues after that, I'm inclined to think there's a problem with the action tube/bars or the shell latches/extractor but highly doubtful.
