Lyman trigger gauge ?
will the Lyman digital trigger gauge measure both stages of a two stage trigger independently ?

Just being careful, I have been able to measure both stages of the SIG P210's two stage trigger with the Lyman digital gauge.

I’ve had little success trying to measure 2-stage triggers with my Lyman. Maybe I’m doing it incorrectly.

rock185 would you share your procedure for measuring a 2 stage trigger with your Lyman ?

rebs, I am tardy responding, but using the gauge on my SIG P210s for instance, I apply pressure slowly. At the end of the first stage, a slight hitch/shelf will be felt, and can be measured at that point. Adding pressure till the trigger breaks gives the total. For instance, on my 210s, the first stage averages 2.5#, then about a pound more pressure for a total of ~3.5# indicated on the gauge will allow the hammer to drop.

rock185 Thank you for the help, I appreciate it. I did it like you said and it worked perfectly. On my Colt match competition AR I installed a Geissele trigger and it measured 1.5 for the first stage and 1.0 on the second stage for a 2.5 total. This is a target rifle only

I think what counts is the stage that breaks the sear.
So unless it read 2.5 when it breaks, its a 1 lb trigger. No issues with hat for target, lighter the better in my view. The test is a hard bolt closure does not trigger off a round. While I have not encountered it, I don't care if the safety works or not. I single load and never use the safety for target shooting. Probably standard, you have to have an open bolt and empty mag for a cold range call.
