This is a special note about the early model Contenders. You may view multiple YouTube videos on proper de-cocking the action. Always engage the safety. There is one other item to build your awareness: DO NOT holster or store a loaded model with the no safety hammer. If you should dry-fire the trigger the internal safety is dis-engaged. The hammer is now live! The secondary safety is now the only protection. The safety hammers are readily available. Please replace it.
