I've been experiencing light primer strikes with my M&P CORE (spec are listed below) and its driving me crazy! I've tried new strikers with 6lbs striker spring, light to heavy recoil spring, cleaning out the striker sleeve every 200 rounds and still the same thing. Every 30ish rounds nothing goes bang. Anyone else experiencing the same issue and thoughts of how to resolve it?
