I took one apart. Nice MIM sear and override, but a bit more stoning doesn't hurt. If you want to get after the overtravel and engagement, yep, you have to rip it apart. I didn't like the idea of heating the trigger spring or burning something else.
The little tiny clip for the trigger pivot is a bear to take off, use your best seal picks, you'll need them.
Then, and only then, can you burn off the epoxy. You can replace the pin clips with .125 or so E-clips from the auto store, which I did.
I am now looking to get rid of the pull-weight spring, find something with a softer and longer tension curve, the stock springs rise rate is too steep. And BLUE locker from here on out, thanks.
