Cheap RO trigger improvement

Someone may have already posted this?:
To improve the trigger on an RO, replace the very stout 30lb mainspring(hammer spring) with a reduced power one from Wolff. They list them for the SA ILS mainspring housings. - We got the lightest, the 24lb--buy the 3-pak & share w/ friends?--
The lb numbers might sound heavy-Trust Wolff. -- A touch of Neco-MolySlide on the sear/hammer hooks and I think you'll notice REAL improvement.-We did-lightened pull to nearly 3.5lb & no problem with ignition. Helps function with a 22Lr conversion too.-- -- Don't forget to use the little take-down pin when removing the housing. Russ OR

ISMI springs are really nice. I have a 17lb one for use with my Marvel conversion, and 20lb ones for my .45s
