I've been playing with the controls on my new BD pistol (not fired or loaded yet). Let me understand this. The decocker serves to take an SA rnd (hammer back), and send it back to DA (harder trigger pull mode) hammer down. If so is this only if the chamber is loaded? I've had the hammer back dry and the decocker lever did nothing most times. Occasionally it would decock. Most times not. The first rnd is always DA followed by SA mode for the rest of the mag? Unless you decock? Some***** is heavy...lol...
