Those EM Pistols looked really cool, like actual guns as opposed to the bulky "ray gun" like phase pistols. I always thought it a shame we never saw more of them. Hell, Borken Bow was the only time we saw one fired, I think. The MACOs left them holstered most of the time.
Hell, I wouldn't have minded the use of "phase pistols" if they had used that design for them.
