I got them and they are quality. I finally got to the range to give them a try. They do exactly what they are designed to do. They allow a locked secure grip without adding bulk or length. The pinky is still allowed to tuck under grip but the gun locks between the pinky and the ring fingerI'm easily distracted. I just placed my order. I'm excited to see how I like them and if they pinch less than the GAP.
That said they still pinch my ring finger so I’m back to the stock mag baseplates.
