Randall knives with antler are secured only with epoxy. They stopped pinning in the late 50's, or 60's. No real need to pin, but no harm either. To look correct for early knives though, they should be pinned, or go all the way through and be peened over a washer on the but. I would still use epoxy however. Either method. It makes a good moisture seal, and insures that shrinkage will not loosen anything while adding yet more strength.
