The GG&G side saddle shell holder carries six 12 gauge shells on Mossberg 500 and 590 shotguns. Its angle helps you load from the bottom into both the magazine tube and the chamber. It installs with no modification to the gun and uses a non-marring backing plate. It works with short tactical-length forearms; longer sporting forearms must be replaced first.
