Things learned from the Miami Shootout:
1) have a good holster that will secure your handgun and permit you to draw it when you are seated in a car, so that you don't feel the need to remove your handgun from your holster in preparation for a car stop.
2) Have a long arm (carbine or shotgun) secured yet quickly available to you.
3) If you need corrective lens to see to aim your firearm, then wear contacts or secure your glasses with a device so that they will stay on in the event of radical movements.
I think that if half (or even two) of the eight agents had had carbines (such as the Colt CAR15 in .223) the fight would have ended sooner in the FBI agents' favor.
