I got new glasses a couple of weeks ago after I realized that my prescription had changed and while the new lenses helped I was encountering a hard time with the sights on my Ruger LC9S-Pro.....all of a sudden the sights were too dim and small.....I thought about upgrading to a different pistol with larger sights but on a companion site a man was talking about a similar issue.....he thought about upgrading and finally settled on brighter sights and he was satisfied......I then thought about it and I am a big fan of XS Big Dot sights and so I ordered a set and installed them today.....a few challenges but the sights went into place and man am I happy with the new bigger sight; the big dot really catches your eye and the result is I saved $400 to $500 and gained my satisfaction back.....so I am suggesting to think about the options.....unless you just want another gun.....
