These were quite common in my early LE days. For single action shooting they provided more contact surface on the trigger, thus a lighter feel. Many cops. me included, carried them on duty. I never heard of a malfunction, such as holster interference or loosening. All the departments I knew of allowed them.
The most common qualification course then was the FBI PPC course, which also became the standard competition course. As more and more really skilled shooters (not me) got involved those pioneers struck upon the idea of shooting the entire course DA, even though SA was allowed at 50 yards.
I arrived at this same conclusion. I decided to change to DA all the way through. It took me 3k rounds of concentrated practice to make the transition, but my scores went way up. Off came the trigger shoes. The hot set up from then on was a narrow smooth-faced trigger. For as long as we carried and shot revolvers that was the preference.
This is still so habitual with me that the only way I shoot a DA revolver is DA. My non-LE friends think this is very strange - until I start to shoot.
So in the natural evolution of things trigger shoes became pretty thin on the ground.
But not quite forgotten. Some years ago I bought a Ruger 77/22. Despite their sometime reputation of being poor or inconsistent groupers, I was determined to make mine a sub MOA grouper. I put a lot of money into it, including an after market trigger. I wanted that trigger to feel even lighter by having a broader contact surface, so I installed a trigger shoe. All this worked. I no longer shoot competitively, but if I get into an informal .22 rifle contest, if I lose, it will be because I lost, not my rifle.
All of my DA handguns have narrow smooth triggers. But on my 77/22 the wide trigger via the shoe is perfection.
For the OP I think is just a matter of personal preference how he chooses to equip and shoot his revolver. If his preference is SA then maybe the shoe will be a benefit. For DA, based on my experience and what I have seen in shooters way back, the bare trigger is preferable.
