actual product does not match picture/model

This Mossberg 590A1 (version# 51414) is supposed to have a stock with Plus 4 Shell Storage. This is also shown on the picture as well. But I only receive a shotgun with a regular stock, no plus-4-shell-storage. Besides, the pump release is too short to be reached while in firing position, comparing to my other Mossberg pump shotguns. The pump release is so short that I have to move my hand to the other side to reach it.
