Schapman43,
I went through the same thing,bought a S.A. mil-spec,had it for 6 months, it shot low, had to file front sight down to get it to shoot to P.O.A. anyway, after about 6 months, I figured out that this wasn't what I really wanted, so I traded for a Kimber Custom Classic, with an adj rear sight, I love it! this is more along what I had in mind,Suggest you shoot your pistol for a few months, and think about what mods you really want/need, and if cost,and installation of mods is worth it, compaired to upgrading to another pistol with the mods already installed, it may be cheaper to swap for something that has the mods you want and pay some$$ rather than to buy all the parts and have them installed, 1911's are like AR's.... endless customization available.
