skamaniac,
I've been looking for a FO front sight for my BH .45 convertible without success. A friend that shoots matches with me works in an archery shop. Using files and a drill press he modified the front sight on his Glock 34 to accept a FO rod used on bow sights. A lot of work, especially since he could have bought one for his Glock for a few bucks. Don't know why you couldn't do the same if you are the handy type. As for me, I'm trying to con my friend into making mine! I have the FO front sights on a couple of my match guns, Glocks/CZs/ and 1911s. They really help in picking up the front sight quickly. Good luck.
