I also have Tru-Glo sights (5000 and the 2000) both have the Tritium glow pins and both work great! the 5000 is micro adjustable, the 2000 is not. Both are all metal with a one piece head (no screw on guard). If you plan on target shooting then the micro adjustable sight will come in handy. If you hunt more, then Iwould go with the simple and light weightdesign of the 2000.
