I bought a Cylinder & Slide sear spring to hopefully reduce the trigger pull on my Springfield Loaded. Can I just unpin the mainspring housing (after capturing the spring) and slide it down and out, flip up the hammer pin and sneak the sear spring in? Or do I have to go further like take off the grips and pull the ambi safety and grip safety? This is my first 1911 and I'm mechanically inclined, and have stripped down other guns. I watched some disassembly videos and it all seems pretty straight forward. I just don't want to take it down further than I need to. How does the ambi safety come off on the right side? It looks like there's a tab that runs underneath the right side grip. I'm assuming if the right grip is off, the right side safety lever will side up and out? Thanks for the help!
