Happy new year every one!! I have posted this in the Springfield area, but thought it had relavence elsewhere too. I have a SA GI and have recently been educated on the relation between mainspring weight and trigger pull. SO, I`ve been thinking about changing the mainspring and other MSH parts. I`m not too worried about replacing the ILS MSH itself, just the internals, unless someone offers me compelling reasons to replace everything while I`m at it. In trying to research the parts necessary to do the swap, I`ve become a little confused:hairpull:, since this would be my first attempt at this. What all parts are necessary for swapping into the ILS MSH? If I choose to replace the MSH too, do they come complete or would the internals be required also? Thanks for your help.
