Gen 4 G-19 new sights (Dawsons or TTI)

[Gio]

just went to the ameriglo web site to confirm the dimensions of the sights.

I think in classic, terrible Ameriglo website fashion, the height of the rear sight they list is measured from the bottom of the dovetail to the top edge of the rear sight. The important dimension for sight height calculations is the top of the slide to the top of the rear sight. If they are listing it as .256, it's likely .185" high. With the TTI's, you'd go to a .245" high rear (.059" increase) and a .235" front (.070" increase), resulting in a net 0.011" change which translates to a 1.5" shift down in POI at 25 yds, exactly what you need. You may want to verify the rear sight actual height over the top of the slide before ordering though.
