Normal factory SXS trigger pull weight?

[MD*GSP]

Excellent Craig, thank you for clearing that up because what you laid out is precisely how I understand trigger pulls although, I don't have hands on experience to match my understanding of such.

I personally don't buy the fact that friction at the levels we're discussing will cause undue wear but, that's okay. Further, if the edges are sharp and clearances are correct, the trigger should "break like glass"..as the saying goes. Further still, proper clearance will ensure no rounding of the leading edge of the sear with use.

Thanks again for the good post and the detail offered.

*edited to add: if one hasn't the experience and right tools (pinned jigs and a microscope) it's best left to someone who does..great pc of advice, Craig.
