I disagree, you should absolutely feel confident that you are handling a gun safely and unease should never be a part of the equation. A magazine disconnect complicates safe gun handling by adding an unnecessary extra step.
In general I feel less safe handling the guns I own with a magazine disconnect than the ones without. Having to put a magazine into the gun to drop the hammer puts me on edge every time.
Well yeah, shooting someone at all is “intent to kill” regardless of what part of the body is shot.
