Tinkering with the idea to replace my snub nose with a Ruger SP101 3" 357 Mag. A little more heft to it which should make shooting .38 more fun, a longer barrel for better accuracy, and the option to up the caliber to .357. One of the downsides of that particular model is the front sight. If I go that route I would like to replace the front sight with some night sight or what have you. Anyone gone through that process? I don't have a machine shop, so anything beyond simple tasks would need to go to the gunsmith. Any thoughts are much appreciated.
