The invention claimed is: 1. A handheld, gas propelled missile launcher comprising: a barrel having a durable, one-piece, substantially cylindrical bore, said bore having a muzzle end including rifling, transitioning into said bore's surface, a ballistic module dimensioned to be received with said bore, said ballistic module including a payload spaced from one single gas cylinder by a gas cylinder opening means, a handle at an end of said barrel adjacent said gas cylinder, said handle including a spring-biased actuator stem remote from a sealed end of said cylinder, to move said gas cylinder against said opening means, and a retainer with a conical bore attached to a disc-holding opening, and a plurality of bores for gas passage, wherein said barrel has a muzzle area and said muzzle area includes an interior rifling configured with elongated channels with a radius corner at each side of the rifling channel spirally deployed within the interior bore, said rifling providing rotation on a propelled fabric projectile to determine improved stability of trajectory, improved range due to a 25% velocity gain and prevented loss of energy up to full penetration, and wherein said launcher further comprises a rotary buffer-safety device, comprising an annular band with a thumb tab, said annular band being captured within an annular track way at an end of the barrel and adjacent to said barrel, said annular band preventing the stem from advancing far enough to contact the cylinder unless the safety device is in its unlocked position whereat its port aligns with a track way for an actuator. 2. The launcher of claim 1, wherein said ballistic module supports a retention ring on one end, the retainer, a disc and an abutment which provides a stop member for said disc at the end of a gas cylinder chamber remote from a flange of the module, said disc having a striker pin. 3. The launcher of claim 2, wherein said disc exhibits a raised boss remote from said striker pin and includes a plurality of discreet gas passage ways passing through the disc, radially offset from the center of said disc with said striker pin, said passage ways having a wide discoid opening at the first end, whereat said passage ways are narrowing as said passage ways traverse through the depth of said boss, exiting its second end with a smaller discoid opening, entailing an acceleration of the air and collimation or focusing of expelled contents of said cylinder. 4. The launcher of claim 3, further comprising said retainer completely enclosing a cylindrically shaped mouth portion of said cylinder when coacted by said stem. 5. The launcher of claim 4, using said fabric projectile being inserted into a sleeve, and unfurling during flight for more stability and improved trajectory. 6. The launcher of claim 5, further comprising a loadable nose cone sealed in the sleeve and a tether, defining its payload, connected to a nose cone and a spool, to pay out said tether while a remote end of said tether remains in the launcher. 7. The launcher of claim 1, further comprising: two pressure balanced springs including a slide, an actuator spring with a spring retainer for said actuator spring, and a return spring with said actuator stem, said spring retainer penetrating an opening contained in said barrel when deployed, accomplishing loading and firing as well as setting said slide at rest. 8. The launcher of claim 7, wherein said balanced springs are deployed for providing: a median position when said slide is resting, a first maximum, deployed position with compressed said actuator spring and expanded return spring, a second maximum, fired position with released said actuator spring and compressed said return spring, wherein said slide is moved into the breach area, and a medium rest position with slide rebounding when said springs are offsetting. 9. The apparatus of claim 8, wherein said track way comprises: a first notch that fixes actuator in deployed position, and a second notch that secures actuator in balanced resting position. 10. The launcher of claim 7, further comprising an actuator operatively connected to said slide, projecting up from a track way, said actuator movable in said track way, said track way having two notches. 11. The apparatus of claim 1, wherein said rifling is formed during an injection molding process by an improved assembly construction being capable of withstanding 5,000-10,000 psi. 12. The launcher of claim 1 wherein said handle is formed as a molded monolith with a hollow central core extending longitudinally along said handle's entire extent, said handle including a gripping area and a door with a cover overlying a recess of the barrel. 13. The launcher of claim 1, further comprising: a pivot hinge connecting said barrel and said handle at adjacent ends, said barrel comprising a spring-biased ball holding a barrel-door captive, said handle providing a release pin allowing said door to swing open. 14. The launcher of claim 1 including two annular bands, one being a force distribution plug with first and second annular wipers, and the other being an end stopper with an exterior diameter that retains projectile in sleeve. 15. The ballistic module of claim 1 including a peripheral wall stepping up to a larger diameter by a sleeve, said additional diameter transitioning to a plurality of longitudinal ribs overlaying said peripheral wall supportively and rigidly.
