howdy. I bought a TFO set (TG131GT1) for my Glock 19 just for the front sight. it's currently mounted with an AmeriGlo rear (GL-405L), I like the setup but unfortunately the rear sight is too low (or front sight is too high) and the gun is shooting low if I line it up properly. anyone with experience or have a caliper and a set of the TFO sights mounted that could measure the rears? would a GL-406L be a better match or do I need to go even higher? there doesn't seem to be much info about using the TFO fronts with different rears, either that or my Google-fu sucks this morning. I'm tempted to just ditch the setup and go with a packaged set like the Hacks or Defoor but would be nice to get this TFO frankenstein working. thanks. Wanna kill these ads? We can help!
