A blaster that uses the Force for ammo would not, in my mind, be a galaxy wide thing. Bearing in mind the FU to NFU ratio, it would be an item that the vast majority of the galaxy couldn't use anyway.
Nah. Millions and millions of Force guns is silly.
Logically thinking (that's silly, this is Star Wars), who would make the quantities of Force-powered guns anyways? You'd have to put whole Orders to work just making blasters.
While making the idea of a "Force Gun" so then Force users don't have to rely upon a Saber alone, is a very niche idea for most people. When people think of Jedi or Sith, they think Sabers, Force, and Magic. Not, a gun that can fire force powers.
While people in the past have made such items on a unique, or semi-unique stage, its very rare a few between due to the connotations of making a weapon that can fire a force power. Meaning, all you need to be, is sensitive in the force to do so. You require no training of the force power to use it, and arguably, some force powers should be restricted in use due to how powerful or extreme they are.
Minor concepts of a "Force Imbued gun" that aid the user in using the gun, or give them better spatial awareness, or make it easier to see through walls with a sniper rifle are ideas I think would be better, than a Gun that shoots the power of the force itself.
As my time of a Factory Judge and RPJ in the past, I myself, have denied, and been denied weapons of such make and design because of the idea alone doesn't really fit with the idea, lore, or aesthetic of star wars, or the weapon was nearing territory of what could be considered a hand-held superweapon.
No. I do not want to see Force guns going around. Because there are SOOOOO many ways you can make a gun, do some really nasty and powerful stuff. Some of which, Force users themselves would find difficult or nearly impossible to defend against without prior knowledge of the weapon.
A good thought, and your mind might be headed in the right direction, but I don't feel its the direction that Star wars, or Chaos should move towards as a whole.
