Pros

+Big glowing front dot acquires fast in low light, much faster than factory 3-dot plastics
+Photoluminescent ring charges under any ambient light for visible daylight pickup
+Suppressor height co-witnesses through an RMSc optic on the 43X MOS
+All-steel construction replaces the brittle factory polymer sights

Cons

−Big-dot philosophy is polarizing, some shooters prefer a smaller front post for precision at 15+ yards
−Taller profile can print slightly more on deep IWB carry
