I installed a Ghost Edge trigger connector, Wolff 4 lb striker spring, reduced power safety block spring, and "25 cent" trigger job. It reduced the trigger pull weight to 3 lbs 10 oz from 5 lbs or so. The hard part was finding suppliers online. Installation was easy using YouTube. Reliability is 100 % and trigger significantly smoother.
I experienced "trigger sting" on my 48 (I have medium/large hands) which surprised me. I installed a DPM recoil reduction guide rod which did not fix it, and a Hogue Handall Beavertail grip sleeve which fixed the problem.
Hope this helps.
