I am installing a Rifle Basix Sav-1 trigger in a little 11 package gun, and no matter what I do I can not get it below 5.5 lbs. Hell the factory trigger is at 4.5. I've adjusted everything, even tried leaving the spring out, but still nothing. Is it possible the sear is a little long and starting the trigger to far back? Bout to pull what little hair I got left out. Any help would be appreciated.
