Yesterday I installed a set of Dawson Precision Glock Adjustable Sights. https://dawsonprecision.com/dawson-precision-glock-adjustable-sight-set/
The factory sights were easy to remove and the new sights installed without any issues. Some early reports have stated that the extra weight of the Dawson sights have had an effect on the guns ability to cycle. This week I will test the same 6 types of ammo that I tested with the factory sights in place and see what the results are. This is the list of ammo.
Eley Force
CCI Standard Velocity
CCI Clean Red (1235 FPS)
CCI Clean Black (1070 FPS)
Aguila Super Extra(1255 FPS)
SK Standard Plus
