Yes, they do have those halfway notches, for the very simple reason that the NAA Mini is not drop-safe!wheelgun1958 wrote:Don't those things have an off-chamber notch?cowboymd wrote:It was a North American Arms 22 revolver.TLynnHughes wrote:Could have been a Taurus, I suppose. There's allegedly a safety issue with certain models when they're dropped. Mine is still currently my daily carry, however.

"The North American Arms Safety Cylinder feature allows the gun to be carried fully loaded. There are halfway notches located between the chambers. The hammer is lowered into one of these notches after the gun is loaded. When the hammer is pulled back to the firing position the cylinder rotates to the next chamber."

If he had an older Mini without the notches, or if he was carrying it with the hammer resting on the cylinder instead of in the halfway notch, then there's your answer: he dropped a gun that will fire when dropped on the muzzle or hammer.
