They've recently developed artificial arms with feeling, allowing you to actually feel with the new arm. It would be relatively easy to make it's artifical muscles stronger than a humans, and the feeling would allow you to be able to fight withou dropping your weapon all the time. However, this is top-notch technology, and you'd have to have boatloads of cash.
