Hey guys, I know this topic is probably beat to death, but I really just need a conclusive answer if I can get one. I have a USP .40 full size LEM Heavy, and I want to convert it to the light weight. I bought a light TRS and FPBS last night, but I'm not sure what I need to do with the hammer return spring, if anything. I'm really looking to lighten up the take-out and the break. Ideally I'd like to get it down to about 5-5.5lbs... I never shoot it from full double action, so I'm not too concerned with the full pull weight, but rather the "prepped" double action. I'm certain I'll see results with the new TRS and FPBS, but I wasn't sure if I should leave the present hammer spring or go with something different. Anyone with constructive feedback would be very helpful to me... Thanks!
