Product information "Walther GSP fixing part"
for grip mounting from below (more stable).
Needed if you want to attach your GSP grip with a screw from below, instead of the two lateral screws.
Conditions:
- corresponding hole below in the frame
- lower frame thickness is 16mm

Attention: Check the screw length for your grip (there are different variants). A screw that is too long can damage the frame!
