I'd ask Kirk or whomever you send it to set the triggers at 3.5# on the first & 4.5# on the second. Those are my personal prefs, but they are shared by many others & w/reason. Aside from what is already mentioned, those settings are adequate for good feel across most any ammunition you will use w/o being too light plus having the second trigger a pound heavier also helps to preclude the tendency otherwise to sometime bounce it or 'double' as in a very quick [read also uncontroled] second shot. I honestly don't know of many seasoned double gun two trigger shooters who wish them set the same, exceptions excluded, of course;-)
Just my two cents, but you can confirm that line of thot w/Kirk & see what he says &/or suggests.
Good shooting irrespective of your choices.
