On an older rifle, the trigger guard often needs to be tightened or adjusted and this does change the trigger pull. Of my two No. 5 LEs, one is .303 with the original trigger guard and is perfectly set up the way I want it. But I wouldn´t like to take it out for any length of time in any weather (i.e. under service conditions). The second (.308) has an action hung trigger. It feels just a bit different ("brittle" or "harder") but I regard it being independent of the trigger guard bolt as a great advantage.
