The front sight came off my Ruger LCP custom the other day and lost someplace on the range floor. I contacted Ruger, and they said I needed to send the slide back to have it replaced. However, looking at the hole in the top of the slide, it looked a lot like the hole in a Glock slide. I took a Clock front sight I had lying around, and it fit right in. I haven't shot it yet to see if it shoots point of aim, but as far as I can tell, it's the same height as the factory sight.
