Replace the sear housing block with a new one with the 1/8" sear spring and it should fix your problem. If you don't already have it, install the new "H" marked trigger bar and the Gen 3 slide stop while you're at it.

kbr, does your gun have a trigger stop screw? If so screw it back into the housing a bit.

You might want to pull the plastic striker liner out and inspect it. I just pulled mine out of my shield 45 today because i was seeing evidence starting to happen with light primer strikes. Brand new shield couple weeks ago, and the liner was breaking into pieces. The pieces were lodging up inside the striker and jamming it up. Worth lookin at anyway... and while its out for inspection, and its all ok, good time to clean it out. Dont lube it when you put it back together, it needs to stay dry to work properly.
