Get a quality holster that won't allow you access to the trigger guard. Flimsy holsters or holsters that do not cover the trigger provide poor safety. The holster is a combination carrying device and safety device. Treat it well.
When holstering, make sure your shirt is clear of the holster so it doesn't get caught in the trigger. Make sure the strap (if applicable) is clear.
The big thing to remember about the four rules is that they always apply. They create safety by overlapping. Don't point a gun at someone because "I checked, it's empty" and don't forget to keep your finger off the trigger just because it's pointed in a safe direction.
One thing someone else on this forum said in another thread: don't get so wrapped up in knowing what you do, that you forget to do what you know.
In other words, just knowing the rules is pointless if you don't practice them.
