It depends on what type of gun you really want to use. SMG pulls out faster,(Skorpion.) has a high rate of fire, but low damage. AR has medium draw rate (M16A4 or G36E.) good fire rate, good, but not great damage. MG has slow draw, which negates trying to quick draw, (Any Mg in general.) but has GREAT damage, semi-good Foire rate. I only use Double barrel shotty for shotguns, because it's quick to pull out, GREAT damage if you right click, but the Rate of fire is slow and could get you killed if you don't aim correctly the first time. Another sniper...We're talking about quick draw here, negate this all together. A pistol and knife, however, are still the quickest choice and the easiest to use.
