I had an FM Hi Power and practically cried when I sold it. FM's are excellent pistols.
You can send the slide to Novak's and have them replace the sights with something that you would prefer. I'm partial to low profile three dot sights myself. If the feedramp is humped, you can also have them de-hump it and polish it and throat the chamber. They do outstanding Hi Power work.
Welcome here. When you get the chance, head over to the Introductions thread and introduce yourself to the gang.
