I'm a big fan of the HD front and have them on the vast majority of my Glocks; the few Glocks I have without them will be upgraded when their current lamps dim. However, I'm not a big fan of the Trijicon rear sights because they are fricken HUGE. Not only are they big, they are sharp as hell and cause fraying of my shirts when carried OWB at 3-4 o'clock every day. They also cut into my luv handles when I bend toward my strong side, but that's another problem for a different thread. Anyway, I've out fitted my Glocks with the AmeriGlo ProGlo fronts (made in conjunction with Trijicon and indistinguishable from the HD) since their front sight can be ordered separately and matched with any number of more reasonably profiled rear sight options. I wish to hell that Trijicon would follow AmeriGlo's lead and have an option to just purchase the HD fronts.
Now, I'm faced with a rather expensive problem. The problem is that AmeriGlo does not offer the ProGlo for popular brands such as Sig and Novak cut 1911s. Thus, I'm faced with several (think 7 or 8) 1911s and an equal number of Sigs with old tritium lamps that need to be replaced, and no way to upgrade to HD fronts without purchasing the Trijicon rears that look like the Statue of Liberty standing proud...ugh.
AmeriGlo or Trijicon, if you can hear me - make a stand alone Novak cut 1911 HD front. I will buy LOTS of them often. Alas, I wait...life sucks.
