I have a S&W 29-3, 44 Mag, 10" barrel and the factory 4 way adjustable silhouette sights. My eyes are not what they used to be. I would like to keep it factory so no milling, drilling, tapping and I am slightly against painting. Is there any company that makes a drop in fiber optic for the front sight? I already emailed HiViz and they do not have anything. Any ideas would be great. Attached is the front sight style I found online
