I looking for a Springfield Mil-Spec as an range-only and CCW pistol. If I order this weapon can I specify the factory add good sights in place of the small GI sights, I would think so, but I don't know. I want a Parkerized version, kinda an everyday gun. How is the reliablity factor on this pistol or will I need to have Springfield Custom Shop do some extra work so it is 100% reliable out of the box. OH, most important question...do they make a Commander size? I normally carry a G29, but I just love the fit and feel of the 1911A1 clones.
