I might have several pump shotguns. Some might be Model 12 Winchesters that perform flawlessly. One is Winchester 1200 which is a PITA. If you are very careful when loading, you can end up with one hell of a mess. The last one up the magazine doesn’t catch if your not careful and you end up with the action closed with one in the chamber, one under the carrier and one in the magazine. That is a mess and a pain to remedy. Probably needs a good cleaning.
That works out well in a Benelli. 7+1+1 capacity.
