Update Ameriglo FBI Sights - Size Comparisons



I received a lot of feedback and requests for size comparisons against the Ameriglo FBI sights and the Trijicon HD sights.


Front Sight Comparisons:



The HD sights are 0.144 wide front blade and about .215 tall, as per the Trijicon website.  I used the Ameriglo Defoor all black sights as a known reference.



The Ameriglo Defoor sights measure .115 front sight so these are at around .125 front.  Since .140 would be substantially more and there needs to a minimum size for the orange his visibility circle.  

Rear Sight Comparisons:




As you can see the U-Notch is very much bigger than the HD's.



It also appears to be slightly deeper and possibly closer to the slide after install.
