Mark the sear with a blue shapie, assemble the trigger set. With or without the slide, dry fire . Without the slide , drop the hammer on your thumb, so as not to hit the frame.
10 times or so. Remove the sear, now look and see how the hooks are swiping on the sear face?
Do this any time you replace or drop in any trigger parts.
Buying a trigger package, dropping it in, does not guarantee your getting equal contact from both hooks on the sear!
How do you know for sure? You don't...until you can verify it.
Even a kit from Brazos. You need to "see", there is equal contact from both hooks! If , your not... no bueno.
Especially, with a trigger pull under two pounds.
When cleaning the lower portion, mark the sear with blue sharpie, assemble. So, the next time you clean and remove the sear, you can see if there are any changes in the contact points!
Thanks, to " powder finger"!
