I came across a champion that was born in 1992. Does anyone know if there is a beavertail grip safety besides Wilson that can be installed WITHOUT modifying/cutting the frame? I would imagine there must have been a few produced back then. Dumb question #2. Wilson has two listed...government and commander size. I'm pretty sure it takes the full size government MSH and beavertail, But not a 100%. Any info would be greatly appreciated.
