Left handed here.
For any handgun with a slide release lever, drop magazine with left trigger finger. Insert new mag with right hand. Drop slide with left trigger finger on slidecatchreleasetakedownpin as right hand moves back into support position. Resume shooting.
If the slingshot method is used, grasp rear of slide with thumb and curled forefinger of right hand, pull back and release.
Been doing that for 47 years and a bit late to change.
When TAK always talked about the dead man’s gun or whatever with the M9 where a person grasping the slide accidentally puts the safety on I always wondered how someone could do that, then realized he was talking about people wrapping their hand over the top of the slide so the thumb pushing down on the safety engages it. With thumb and forefinger the forefinger is curled around and under the safety so the only way it can pull is up which never engages the safety.
I forget which manufacturer, maybe Ruger for their Mk series .22’s or Kahr, advises in their manual to always use the slide release lever to drop the slide on a fresh magazine, never slingshot as the slide release method always results in more positive chambering of the round.
Just an addendum, but IIRC that slide release drop was how we were taught to do it in Army basic training. Those 1911’s we used for training had likely been in service since Korea and the slide notches were still working like they should.
