My suggestion: get an indoor dog and have it sleep in your room. That will buy you a lot of time.
If you must lock your gun up, just lock it when you are not around.
At night, unlock it and put it under your pillow. In the day, wear it or lock it up. That is my opinion around toddlers.
There are also a variety of good locks that are easy to disable by an adult. One is a big rubber band around the slide of the gun (stretches from the muzzle, back to the hammer). The band holds the hammer down and if it is a DA it cannot be fired until the rubber band is slipped off, which takes adult strength and unfortunatly two hands. In the end I know of NO lock that is instantly accessable by on hand, with someone beating your face in. The gun has to be ready.
Fact is, TRIGGER LOCKS DON'T WORK. They are dangerous to install, can cause the gun to fire and they render the gun useless. The only thing you can do, IMHO, is to make the gun safe in the morning when you get up (if you choose not to carry it) and then make the gun ready before you go to bed and keep it near.
I like my Glock with a Saf-T-Lock on it. It is a doo dad that clicks in behind the trigger and can be popped out
