This GLOCK OEM 4.5 "Minus" connector has been plated with CTI"s proven NP3 finish for a reduced trigger pull weight without potential reliability concerns that may arise from use of aftermarket connectors. CTI's NP3 provides a smoother operation with less lubrication (Phrasing!), and its maintenance free nature eliminates corrosion concerns. This connector will reduce pull weight approximately 1/2-1lb based on specific frame and parts tolerances.

NOTE: This connector is not compatible with Glock models G42/43/43X or 48 slimline models. Only intended for FULL SIZED Glock firearms
