If you want to reduce the wall feel that some trigger kits have for a range gun...would you bevel the inside of the trigger bar curved tip that rolls over the lip of connector,also if so,would doing this lesson the reset snap upon return...or is it something else entirely...
I'm not sure what you are asking about - What I would interpret the first part of the question to be about is a different event than I would interpret the second part to be referring to.
I would have thought the first part "wall feel" to be referring to the second stage of the trigger pull. Where you can feel the trigger bar make contact with the connector, there's a fairly distinct change in the trigger. From that point on is the real weight of the trigger pull which you've been working on. I'm not sure how one would lessen that since it's when two parts make contact without also making the trigger so light it would be unsafe. i.e. you had your pull under 3lbs and I'm assuming you could still feel the "second stage."
The second part though, you ask about "beveling," "rolls over the lip" and "reset snap" - that leads me to believe you're referring to when the connector is pushed over by the slide which allows the trigger bar to raise back up in order to catch the firing pin lug. This happens during the slide cycle, which includes recoil so it happens during a pretty violent action. I'm not sure what kind of a "wall" you would be able to feel during that process.
Hope this can help you refine the question a bit.
You mention trigger kits - are you referring to one that has an over-travel stop?
