In case any one ever needs to replace the Mil-Spec sights on their Springer, I found these direct replacements at Fusion. As you may or may not know the front sight tenon is neither the wide or the narrow tenon that most places sell. It is in between. These are nice sights and are pretty cheap in cost. Fusionfirearms.com Sight set, White Dot Springfield Armory 1911-A-1 Series Mil Spec I would think that should get you real close. They are well made and like I said, a direct replacement.
