After researching current 1911 products to buy I've decided to go after a Springfield. The only thing I have any concerns about with making this next purchase is the front sight. On the full size 1911A1 it apears to be part of the forged slide (correct me if I'm wrong). Does Springfield offer a dovetail front on any of the higher line pistols (TRP etc?). OR is it relatively easy for a smith to remove and mill for new sights if desired?
