I have such a version. I didn't realize that was one of the stipulations. I kind of thought my trigger pull was a bit "heavy". I just bought a Sig flat trigger, which may help out leverage wise, but that won't even get me to what the factory standard must feel like! I didn't want to have to do the whole trigger bar thing, but maybe I will have to."-MA" models also come with a 10 lb min trigger pull weight.
