Cleaning my M&P the other day after is surpassed its 8,000th round I noticed the striker is getting a little sticky. I removed the striker and noticed the finish has worn around the base of the firing pin and directly behind this point right near the top of the shoulder. I cleaned the striker and the stricker chamber with an well known over the counter, synthetic friendly spray solvent (only descriptions today because I actually forgot the damn name
, must be a premature senior moment). This did not seem to help. When I push the plunger up and advance the stiker forward it protrudes into the breach but does not retract back on its own. I dry fired the gun numerous times with snap caps and did not find the firing pin protruding.
Should I be concerned? Is there a better way of cleaning the striker and striker chamber?
Dan, hhhheeeeellllllllpppppppp! Of course, anyones advice is truly appreciated.
