What it is
Ian McCollum of Forgotten Weapons examines and fires the ArcFlash Labs GR-1 Anvil, a portable shoulder-fired gauss (coil) rifle. He explains how its eight coils, optical gates and capacitor bank work, and how a 25V lithium-ion battery charges the capacitors in about 3 seconds to launch a steel dowel pin at roughly 75 m/s.

Interesting: A video explaining the function of an **actual, real-life railgun** [this video] , which is also being fired. Firing starts at 18:20, but to be fair, the whole video is interesting.

In short (links to follow as I find time to put them in). Coil guns (aka Gauss guns) Have a higher max projectile velocity. Powerful switches alternate the electromagnetic poles in the drive coils as the projectile passes through the coils. This requires high voltage, high amperage, high speed electrical switches. Researchers have been trying to build these for decades with only moderate success. is a type of projectile accelerator consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity. 1 [LINK] In almost all coilgun configurations, the coils and the gun barrel are arranged on a c

Assumptions For the purposes of the question, in my world technology has progressed far enough that the power supply problem and the rail/cannon durability issue are solved - all of that is handwaved. Human civilization has advanced far enough to now have a technologically viable handheld railgun. Question For equivalent bullet masses, and achieving equal muzzle velocity, how much of a difference in recoil would there be between a railgun and a conventional firearm? To simplify among the plethora of options, let's examine the most used caliber worldwide, .38 or 9mm. (I am aware that the same caliber can pack more or less punch.) Since we don't have a handheld railgun blueprint available, I'm
