I own a M&P 9mm and have a question about cleaning and maintenance. The way I am cleaning now is taking the barrel out, cleaning the entire slide etc. then cleaning the bore out after each shooting session. My question is, should I be cleaning out the striker mechanisms, and inside where the firing pin is etc. as well the trigger mechanisms etc. and if so, how is this done? how do I take it down easily past the basic field stripping? This is my first striker fired pistol. Thanks all!!
