S2 Mods: 8.5lb hammer spring, 11lb recoil spring, extended firing pin, and reduced power firing pin spring. That's all for now. 6lb DA and 2.75lb SA. Practiced with 200 rounds on Friday. Shot a match with it on Saturday. Not a single issue. Fed primers, of course. I like the balance of the gun better than my two other Shadows. I will be putting a new disco in to shorten the SA reset when I get the part from Seboweapons. I also need to polish the internals soon.
