I just put a Neotech Grip on my 6H. Osteoarthritis in both hands and wrists made it necessary.

I only needed the straight bushing, so I have the curved and gusseted ones left over. If you want one or both, PM me your address and I’ll drop it in the mail. Would rather they be used than lounging in “that drawer” with the rest of my junk. I’ll include the shims and screws I didn’t use.
