So I have a set of grips for trade in the MP and a member offered me a set of Blackhawk grips and he and I were both wondering if these are interchangable
Blackhawk grips will interchange with Old Army grips; both use the XR3-RED grip frame. The New Model Blackhawk XRN-3RED frame is dimensionally the same as the XR3-RED, so New Model Blackhawk grips will also fit an Old Army.
