Would coil gas expansion hybrids hand gun be viable weapons in the near term future?
I have a science fiction setting that I would like to spice up with hand held sci-fi weaponry (coil guns, plasma weaponry). However, coil guns appear out of reach. Could you combine coil and gas expansion weapons? Could this combination weapon offset the known power, heat, materials (and other issues) associated with coil guns?
Given what we know today what innovations would make coil gas expansion hybrid guns successful on a near term battlefield ? What properties would make coil guns superior to current hand held weapons?
Context: The environment is current warfare conditions. Assume a battlefield similar the Second Gulf War. Specifically, the United States may choose to use coil guns and Iraq has the same equipment as in the historical record.
Note that these parameters are intended to guide not interfere with responses. You have license to adjust parameters to prove a point (for example change the Second Gulf war to the Vietnam War).
Feel free to add formulas such as KE = 1/2MVˆ2
