G17 Sight Help

[hank2165]

I train at 25 meters consistantly. I have Trijicon sights on my G17 Gen3. I'm using a NRA B8 bull target. Problem is I have to aim approx 1 inch below the black to hit the 10 ring. Should I use a lower rear sight? I know it's a pistol 101 question but help needed on this one. I've been shooting the gun for a year or so and have been to several courses. I'm also quite proficient but would like to not have to compensate.
Thanks

You're not going to have options with the Trijicons.

Just know your zero.

I bought the trijicons front and rear night site for my G17 and it shot high at 25 yards. I replaced my front sight with .185 height trijicon nite sight and now shoot POA POI at 25 yards. Call Trijicon and order a .185 height front.
SORRY FRONT SIGHT HIGHT POSTED INCORRECTLY CHANGED TO PROPER SIGHT HIGH OF .185

Just to add I went from 6" high at 25yards to dead on at 25 yards.

I may remove them. Would a lower rear sight do it? I use sight black on the range anyway so switching them out won't kill me.

If you are shooting low you need a taller rear.

Check the Ameriglo website.They have a calculator to help you select the right front sight height to adjust your POA/POI. Their sights also use Trijicon inserts.

You need a taller rear sight or a shorter front sight.

error ∕ distance x sight radius = correction needed

All in inches.

For you that would mean the following

1/900 x sight radious = rear sight elevation

By the way the change in elevation is minute at 25 yard. You could just file the top of the front sight and cold blue/paint it.
