I put Glock OEM night sights on my 43x. I’m having my point of impact unusually and consistently low. I’m having to aim way high to hit center. That rear sight is size 6.1. I keep reading that a taller rear sight will bring the POI higher. The next sight up is 6.5. Some websites say the Glock OEM 6.5s will fit, others say it won’t. I’m trying to find a company that offers a taller rear night sight for the 43x than the 6.1. Does anyone have any leads or similar experience with this matter?
