Dan,
Which is better, four quarters or two half dollars? The question of FLGR (full length guide rods) is hotly debated among 1911 owners. Some love them and some hate them. Both will work. Choose your preference and go for it. I happen to like FLGRs and have one in each of my 1911s (one Kimber and five Wilson Combat guns). I DO NOT like the two piece rods however and use only one piece FLGRs. My target 1911s have tungsten FLGRs for a little more stabilizing weight up front. Note: Browning didn't put fancy grips, stainless frames, black colored finishes, magwells, beavertail grip safeties, or adjustable sights on his original 1911 either but I happen to like these features on my guns.
