I don't think you'll have a problem with the Wilson 13# CS spring and the Wilson trigger bar in your 92. My experience has been solid with that setup, even without the Wilson hammer. Dipping below 13# hasn't been as reliable for me, and I had hoped the Wilson hammer would help with that. I need to put a few boxes of Speer Gold Dot through my pistol with the 12# before I'd be confident in it for carry, but the light strike with the Speer Lawman TMJ has me hesitant (to your point about peace of mind), which is why I was asking about the Speer Gold Dot (specifically G2) primers. 12# has been 100% with Federal primers so far.
