Collecting firearms is a hobby, and some folks want to carry their collections, and give some carry time to every weapon, as if the weapons themselves really care about being left out. No, IMHO, that is a poor strategy.
All of my serious handguns, the ones I would draw or otherwise grab in a hurry, are long-stroke double-action, and they all point the same in my hands. They consist of the SIG P229 DAK pistols I use for duty and most carry, the SP101 revolvers I use for back-up and some primary concealed carry, and the larger Ruger sixguns I use for utility and occasional carry. I can grab and shoot all of these weapons without having think about anything, not even the sights at short distance. Even my Seecamp LWS-32, rarely carried, points well enough, and has long-stroke DA, with the trigger set far enough forward to feel like a bigger weapon.
I also have a couple of P229s with DA/SA triggers. These see little to no carry time. I can indeed handle the DA-to-SA transition, but have figured that since I shoot them no better than my DAK SIGs, except from a sandbag rest, and not always even then, I might as well have one less possible complication when out on the street.
I shoot my 1911 fine, and it points well for me, but I have to remember to place the center of the pad of my finger on the trigger, rather than the crease, for optimum accuracy.
I really wanted to buy a SIG P245, recently, as its grip is narrower than that of my P229s, but it, like its bigger brother P220, does not point well for me. It is also DA/SA, of course.
To be clear, I am not saying that highly motivated individuals, with training time and a budget to match, cannot be proficient with more than one weapon system. I don't have an unlimited ammo budget, and time is precious, especially time to travel to a range where I can practice realistically.
