Ruger makes good guns, and stands behind them. They may not be what everyone thinks they ought to be but they are good guns.
Two things to be aware of, first, Ruger's current "warranty policy". As I understand it, if you send the gun back to Ruger, for any reason, Ruger will return the gun to the configuration it was in when it left the factory. SO, if you install any aftermarket parts, Ruger will remove them. I've never had one of their 1911s but have owned Ruger rifles and pistols since the 80s, never had to send any back for any reason.
The other point, something you might want to check. My son has one of the S&W 1911s and the grip screw bushings do NOT line up with the standard GI/Colt pattern grips. Don't know if the Ruger does, or not, but its something to check before you spend any cash on grip changes.
