The Wilson Combat Guide Rod is a precision-machined replacement guide rod for the SIG Sauer P320 and WCP320 full-size models, brand part number 320-GRS. Cut from hardened stainless steel with a bead-blasted finish, it is profiled to accept a full-size 1911 recoil spring, giving shooters access to a much wider range of commonly available springs to tune the recoil impulse to their preferred ammunition. It is a simple, precise upgrade for anyone who wants to fine-tune felt recoil on a full-size P320 without hunting for proprietary springs.
