The Shield is a subcompact intended for concealed carry. If you're not going to conceal carry it, it is not a good choice. All things being equal, you will not be able to shoot it as accurately as you could a full size handgun and it may even be uncomfortable (more perceived recoil due to the weight and width). Ammunition capacity is also very limited in order to make it thin and light.

The SD would be a better choice for your purposes, but I think you might find better luck with other options.
