This guide details how to properly dry fire an M&P 1.0 pistol. Unlike some other firearms, the M&P 1.0 requires a magazine to be inserted for the trigger mechanism to reset. This is due to an internal metal piece that must be engaged by the magazine. Following these steps ensures safe and effective dry fire practice for trigger control.

Quick Summary

The M&P 1.0 trigger will not work for dry firing without a magazine inserted. This is because an internal metal piece must be engaged by the magazine for the trigger mechanism to reset, preventing a dead trigger.
