Just applied some of my materials to the higpoly model of the "Brotherguard" Revolver.
I think it's worth showing

The two barrels fire the same caliber. The six(*) round drum feeds the upper and lower barrel at the same time. Now there is a trick on the, the hammer and the brass-primer-ish look of the rounds might suggest that the bullets are fired by hitting the primer liek normal revolvers, bu no! That gun is a hightech product! It uses electric ignition ("Metal Storm" could tell you something
). The hammer actualy uses it's energy to create electicity from the impact on a Piezo-crystal, so no battery is needed. Also each of the bullets holds two rounds, you can see the line on them where the second round starts. The revolver fires two rounds at once, meaning that the recoil will have no effect on the second bullet (just like the theory behind burst shots, kinda). The switch on the side enabels to onyl fire one barrel at a time, giving the revolver effectively twelve(*) shot. Other ammo can be loaded, like one shot rounds with obviously a huge load of powder and thus greater power or multishot rounds that are less penetrating but increase capacity. The blade is there because I like all purpose tools, also the balde won't hit the laserpointer when the top is broken down due too internal barriers in the joint. There is still enought space open to reload with a quickloader (thats tested!). The laser itself passes right below the blade, the balde is not in the way even whe the laserpointer is adjusted to slightly point upwards. The gun got a internal calculation system that adjusts the laserpointer depending on windspeed, bulletdrop, etc. (crucial due to different ammo types), the sensors are beneath the front ironsight (the black holes in the crome part). Important data like ammo, distance, etc. is displayed on the red dot sights screen (not visible in this render, but in "making of game model" linked above). The weapon got no attachment rails, the top rail and the bottom rail (with the blade) are purely for supporting the stability of the gun since it is used in melee aswell.
Ok, I geuss that covers all the technical theory I had in mind when creating it
