Which Dawson FO's for a G26?

[Cochese]

I'm looking to replace my front and rear stock sights on my G26 with Dawson Precision front and rear fiber optics. Just like these ones here...

I'm a little confused on the sizing...

For the rear...

018-005
Sight - Rear Fix/DP/For All Glock/Optic, .115" Notch, Requires .205" Tall Front

-or-

018-002
Sight - Rear Fix/DP/For All Glock/Optic, Wide Notch, Requires .205" Tall Front

For the front...

019-013
Sight - Front/DP/For All Glock w/DP Fixed Rear/Optic, .105" x .205" Tall

-or-

019-014
Sight - Front/DP/For All Glock w/DP fixed Rear/Optic, .125" x .205" Tall



I want the red front and green rear. Just not sure what sizes to go with... anyone help out? I'm going to a Armorer school 8/21, so I'll try and install them myself. Special tools needed?

Thanks!

I also wanna make sure they clear my ghetto fobus paddle carry holster and my High Noon Hidden Ally... height wise.

Will they?
