LPA sights fit right on my M9 and work pretty good with out touching the front sight. I am filing the notch a little wider right now. It's not a Sams job, but it works...
I don't know about the 92, but there are none to be found for the 1911.
Several gunsmiths that I've inquired with still have some though - they won't sell them but will install them. You might try David Sams. He works on Berettas and might be able to help you out.
Try Champion Sights. They were at the NRA convention exibit hall in Louisville. Their sight looks just like the Bo-Mars. The 92 FS sight looks like it would require a built up front sight, though.
