As far as I ever understood select fire, it is: semi-auto (one trigger pull one projectile), 3 shot burst, and finally full auto. These require a huge sum of money to purchase and own because of the tax stamp (again, if I recall correctly about 10 grand), a massively long wait for a government colonoscopy and potential OK to purchase, then the actual purchase of said rare weapon that will cost a boatload of money also.
No shit Sir!
