M&P Thumb Safety Models - Proper Sear Pivot Pin Installation
Please carefully follow these guidelines when installing the sear pivot pin in the Thumb Safety equipped model of the M&P. If the sear pivot pin is installed incorrectly, it will directly affect the function of the thumb safety. The thumb safety will not be able to be set into the "safe" position. Proper installation of all parts in firearms is crucial to their functionality, reliability, and safety. Thank you.
