A friend obtained a used Springfield Armory 1911. It had been equipped with one of the full length sight ribs which had been removed, leaving only screw holes, no sights at all. I ordered a set of Colt fixed front and rear sights. The front is the "stake in" variety but I can't see how to stake it, it's not as if one could just stick a punch in there. Does it require some special tool? The tenon was a very tight fit in the slide and I coated it with JB Weld before pressing in but I just see no way to actually stake it.
