I have four leftover but unused Grip Force Adapters (GFA) with the ribbed beavertail (I used the smooth ones that came in the packs). I have three Gen4 GFAs and one Gen123 GFAs. All colored black. Each GFA comes with 2 pins. One per person only. Site Supporters only. Please post if you want one and I'll mail it to you. PM for any questions. Thanks.
