The stock button on the Benelli M2 SP leaves something to be desired…
We’ve created the optimal profile for the release button, raising it away from the port and streamlining the shape to move it out of the way of your quadloads and reduce the risk of snagging significantly. It’s much larger than the stock button and is designed to be obviously different when it needs pressing (i.e. when you run dry) by touch alone, without having to look at the chamber.
