I purchased the 5 inch barrel setup which turned out to be a mistake. Now I am back to the original setup and want to replace the front sight with something more pronounced. I have a bunch of 9mm's but like firing this pistol. I use it mainly for target shooting and have the windage down but trouble with the elevation. Does anyone have and success with a front sight replacement and what make? My wife has a Smith PC Victory with fiber optics which are tremendous. Thank you!
