Questions & Answers
Will this fit my Glock 45 gen 5?

Yes they will.

by L2D, Verified Owner, February 13, 2025
What is the height of both the front and rear sights? And the width of the front sight and the width of the notch in the rear sight? Thanks! Expert Answer

The L2D Combat Co-Witness/Suppressor Height Fiber Optic Sight Set has a rear sight height of .406", and front sight height of .315". The width of the notch and front sight are not provided. I would recommend reaching out to the manufacturer directly for more information.
