I got my X5 back from Sig today for the voluntary upgrade. I measured the pulls and they were 3.5 - 3.8 lbs, the gun was very well lubricated and greased up. I thought this was awesome because before I sent it off it was in the mid/high 5s. Well in the meantime while waiting for the gun to get back I picked up gray guns competition trigger kit. I just installed that with a lot of patience and youtube, then I averaged 5 pulls and now the gun is pulling low 2s. I tried pulling from the center and from the end. I'm worried this is too light. This gun is just for 3-gun fun, and i am no Daniel Horner.
edit: I did have a set of leftover springs in the kit, i'm wondering if they are a higher lb pull.
