I love 1911's. They've often been compared to classic muscle cars, and with good reason. Outstanding design, but not something you'd want in 2020 as your first or only car.
The default answer is "Glock 19" and there's several others that are comparable in function and price.
One thing to consider, which is the opposite of the "little gun for a little lady" advice often heard in gun stores, is that the lighter a gun is the more it recoils. Making it that much more difficult (and less enjoyable) to shoot.
I would strongly suggest taking a 101 class if a nearby range offers it, and trying out as many models as you can before buying.
