Fixed my light strike issues - Ed Brown Products Extended Striker Block Plunger

I've got a first Gen M&P9 CORE w/ the full Apex trigger kit in it and several thousand rounds plus several thousand dry fires on it. In the past several months I started experiencing the occasional failure to fire that progressed to about a 1% failure rate on failure to fire across multiple brands of ammo. Inspection of the unfired cartridges confirmed a light primer strike. I figured I'd throw some money at this striker as a long shot, "just in case..." Simple install on a CORE slide. Imagine my surprise to find DEEP, solid hits on primers of the freshly spent cases! If a cartridge won't fire getting hit that hard now, it won't fire in anything... On top of that, the new striker didn't adversely affect my trigger feel to much. There's a little bit of a hitch in the trigger pull now where there wasn't with the Apex USB, but not enough to matter functionally running drills. This got my main gun back in the fight nicely. Might have to pick up a few more for my other M&Ps now... Good stuff!
