I started using TFO's in early 2006 for my IDPA and USPSA guns. In SSP and Production divisions. I had 4 different fiber optics fall out on the early sights. The sight still worked and the tritium still glowed. The company's customer service was outsatnding with fast replacements.
Since 2009 I have put them on 7 different Glocks - ALL HAVE BEEN FLAWLESS! I have even put them on my 2 G21SF house guns and one of my G30SF car guns. The new sets are heads and shoulders about the older models. I still avoid getting solvent on the fibers optics.
They have made my old eyes function like much younger eyes. Based on the last 2 1/2 years, my personal experience says they work very well with a little care while cleaning. Bright at night, bright during the day and bright in-between.
I don't have them on my 1911 carry guns but I have put a set on my G36 BUG which I have carried everyday for the last 9 months. No issues.
Probably need more data points before I would make a ABSOLUTE recommendation but so far, so good. Contact them and ask about failure/replace rates or trend data.
