A magazine disconnect is not worth having. It complicates the pistol and is just another thing to go wrong. If an officer has time to press the mag release during a struggle for the pistol, the officer can press the trigger. A self loader without a mag in it is useless. If the mag is in the same drawer, the child only has to insert it. If it's someplace else, you're disarmed until you find it. Just Say NO to Magazine Disconnects!" and "Silly Sheeple, Disconnects are for Anti-Gunners".
