A solenoid isn't very advanced, nor is it easily "de-activated" remotely. In fact you could manufacture a gun with a solenoid based trigger group which is an entirely closed system that not even EMP from a nuclear detonation would be able to affect.

@jacobwoolf2010 It depends on the ampunt of energy behind the wave. Electronics dependant on microscopic components would be the most vulnerable to EMP, since they have the smallest conductors, and thus would burn out rather quick, as opposed to 1980's electronics that use much more bulkier components with larger conductors. Even so, all electronics are susceptible to EMP, except if protected by a barrier that won't allow electromagnetic waves of a certain wavelength to pass through.

@Klaaism Naturally. The problem sometimes is that the people being concerned are of soldier backgrounds rather than engineering backgrounds. And engineer would tell you that when it comes to conductors: the thinner the area of the conductor, the more resistance it exerts on the electrons passing through it. Resistance = friction = heat. When operating under normal voltages and amps to which the conductor is designed for, there are nor problems. But an EMP basically cause a massive jolt of current and amp through circuits in the vicinity, which risks burning some conductors out on account of being too small to handle the added energy. Build your electrical components sizeable/thick enough to handle an overcharge and they won't burn out, even due to an EMP. Basically like you'd design any gun for the military: make it rugged and reliable rather than prioritizing small size and lightness.
