Claim:
A method for firing a high-mass/low-velocity projectile followed by a bullet, comprising: a. providing a firearm, including, i. a barrel having a firearm bore and a muzzle, ii. a first cartridge, iii. a second cartridge having a bullet; b. providing a barrel adapter, including, i. an external surface, ii. an adapter bore, iii. an exit; attaching said barrel adapter to said muzzle of said barrel, with said adapter bore being aligned with said firearm bore; providing a high-mass/low-velocity projectile, including, i. a launch tube having an internal surface configured to slide over said external surface on said barrel adapter, ii. a body surrounding at least a portion of said launch tube, iii. a nose, iv. wherein a mass of said high-mass/low-velocity projectile is greater than 0.2 pounds, v. a stun controller, vi. a positive dart electrically connected to said stun controller, vii. a negative dart electrically connected to said stun controller, viii. a first launch tube containing said positive dart, ix. a second launch tube containing said negative dart; e. sliding said internal surface of said launch tube over said external surface of said barrel adapter in order to slidably connect said high-mass/low-velocity projectile to said barrel adapter; f. placing said first cartridge in said barrel; g. firing said first cartridge, thereby sending expanding propellant gas down said firearm bore and said adapter bore, said propellant gas escaping said exit in said barrel adapter and propelling said high-mass/low-velocity projectile away from said barrel adapter; h. placing said second cartridge in said barrel; and i. firing said second cartridge, thereby sending said bullet down said firearm bore, through said adapter bore and out said exit in said barrel adapter.
