The FLGR serves no real purpose other than many expect them to be on tricked out 1911s. My TRP had one, and other than making take down harder, it did nothing to improve the gun. Well, actually, it did cause me to spend some cash replacing it with standard GI rod and plug.
If you had an extremely accurate custom 1911 built with a full length guide rod - would you take it out and replace it? If so, why?
