Hello there. My thinking is that I will need to get a different sear,sear spring and hammer rated at 4lbs to reduce trigger pull in my pt1911ss ar. But I have been reading that some people say that an sti trigger will reduce pull automatically by itself by 1-2 lbs. I have been looking at buying a cylinder-slide 4lbs hammer and sear set, when I get the sti trigger I don't want the pull to be at 2lbs or anything because I carry this gun. any info would be appreciated.
