Hi, I just ordered an Ameriglo ProGlo (.140 wide) and Ameriglo Pro Series black serrated (.180 wide). For my frame of reference, how wide is the Glock factory front sight (currently installed on my Glock 19)? Is it .140 in width? I know the rear notch is significantly narrower than the pro series, but I'm curious about the front sight only because I want to figure what kind of target coverage I can expect on an 8" steel plate at 25 yards. I almost went with the .125 white outline tritium, but them I read a review from someone who raved about the ProGlo, and it looked like viable setup with pro series rear, so I went with it. However, now I'm not so sure which set up would be a good all-round fast set up for near and far at speed (on both larger and smaller targets). My defensive/carry guns are my competition guns, FYI. Thanks.
