Not a fair comparison. S&W puts a hinged trigger on the Shield that is extremely forgiving of finger placement to disengage the safety.
This is not true for many bladed triggers.
The bladed triggers pioneered by Glock and used on the Hellcat are less forgiving of finger placement. That is common knowledge. You MUST place your finger over the safety blade in the center of the trigger and depress it BEFORE pulling the trigger body aft to make the gun fire. Period. This, by design, makes it SLIGHTLY less prone to a negligent discharge than a hinged trigger or a rigid trigger.
Lots of pros carry 1911’s. A sloppy grip in a panic situation when presenting a 1911 will not depress the grip safety correctly resulting in a gun that will not fire. “Limp wristing” any auto pistol with a loose grip risks having it not cycle properly. Are these “design flaws” too? Hardly.
It is incumbent on all of us to know the manipulation limitations of the weapons we carry and spend the hours required in holster drills with PROPER technique to build correct muscle memory. And to repeat that training regularly & often for as long as we intend carry.
If you are not 100% confident that in your hands the Hellcat trigger will never be mishandled by you in a panic situation, either train a lot more from the holster or sell it now and buy a Sig, a Shield, or a revolver.
Center safety triggers have manipulation limitations just like the grip safeties on 1911’s do. We accepted those limits when we bought any gun with a center safety trigger or a grip safety. Know the limitations of any weapon you carry and train to minimize those limits in your hands and to hit only what you aim at. Or don’t carry.
