My brother, GalvinGround, has been debating whether or not he should get a full length guide rod for his new RIA 1911FS. As far as I know the only difference it's going to make is to prevent the spring from potentially kinking. The RIA 1911FS has a parkerized finish, which makes the majority of the guide rods available not very fitting for the finish.
What exactly are the reasons to switch? Which kits have worked best for you?
