If you have the Ruger LCR you have got to get the HI VIZ Handgun Sight
I mostly point shoot my Elsie Ahrrr but when I sight shoot, there's a great deal left to desire. This HI VIZ upgrade is something Ruger should have offered as standard equipment or at least, an option.
I got mine on DVOR
for <$30 and worth every penny.
All you need is a bench block, brass hammer and a 1/16" punch. Drive out the sight roll pin, lift the old sight off the barrel and reverse the procedure to install the HI VIZ light pipe. Maybe 10 minutes including rounding up the tools.
Great addition to my Elsie!
