We've sourced OEM GLOCK minus connectors for the G43, G42, G43X, and G48 models. This GLOCK OEM  "Minus" connector has been plated with proven NP3 finish for a reduced trigger pull weight without potential reliability concerns that may arise from use of aftermarket connectors. The NP3 finish provides a smoother operation with less lubrication (Phrasing!), and its maintenance free nature eliminates corrosion concerns. 

Also, Our lawyer says that this should be installed by a qualified gunsmith.
