The XDs has the ambidextrous mag releases in place and I expect compatibility with 1911 mags would have been tough.
I have the bi-tone XDs 45 ACP. It is a nice little concealed carry handgun. It comes with a holster, but I doubt I will use it.
I prefer the XDs for pocket carry. If I were to carry IWB/OWB, I have better choices, such as a Glock 27 or a 19. I could always carry a 1911 too. The XSs is small and light and that seems to make it good for deeper concealment.
It has manageable recoil, but you need to be firm with it, just as with any smaller handgun. Loose grip and wrist will make it less reliable. It works fine if you do your part.
