I put the APEX Duty Kit in my .45. Took the pull from 8 lbs to 4 1/4 lbs. Super easy to install worth the money spent. Also added the APEX extractor. I had about 1500 rounds through mine before doing the work. It never really lighted up on the pull but the gritty pull did go away. If its pull weight that's bugging you, that won't get any better without a kit. I have seen posts about guys doing some polishing on the internals that made a big difference too. Hope this helps.
My pistols, however, I always kept by me.
