Found a fun glitch. Pick a weapon whose rate of fire you want, weapon 1 for now. Weapon 2 is the one you want the effects of. For now lets use a minigun for weapon 1, and a flaregun for weapon 2. have 2 out, then switch to 1 and almost simultaneously hit reload. If done right you look like you have 2 out. Minigun that shoots flaregun shots=win.
