And there lies the dilemma that caused me to buy several types of guns (including the Shield w/safety) before I determined that for me, a DA/SA, w/decocker, wo/safety, ticks all the boxes.
I determined I did not want a safety on my carry, since I was not going to train with enough reality to know for sure what I'd do with it when the adrenaline flows.
Even though you could flip the safety off, the slight possibility exists for it to become engaged.
Without a safety, I wanted a safer and heavier first trigger pull than most striker guns offered.
With double action guns, I had a tendency of short-stroking the trigger on rapid follow-up shots.
Finally discovered an action type that provided what I sought. A small subset of pistols, DA/SA, w/decocker, wo/safety.
A safe, long and heavy first pull, with a short reset and light pull for followup shots. No safety to ever get in the way.
Back to the Shield. With a safety, it adds an action you must complete before you can use it. Without a safety, the relatively lite trigger demands more discipline to avoid an accidental discharge (Google Glock Leg).
There's nothing "wrong" with whatever you choose, it's just a matter of what you prefer. In my case, it took a couple of years and several guns before I determined my preference. On the bright side, I now own several alternate carry choices.
