Concealing a weapon is not required within your home. If I understand your proprosed scenario correctly...someone unlawfully enters your home...there are many variables to consider, and these are my understandings only, as IANAL (I am not a lawyer).
If it's daylight, it is presumed that you can see the BG before shooting, and therefore are able to size-up the threat before shooting. You're only allowed to legally shoot to "stop" an eminent threat to you or others that you are protecting. If it's night, you are allowed more flexibility, as it is presumed you may not be able to completely determine the degree of threat. However, in either case, if the BG is retreating, it is deemed unlawful to shoot.
You should always have the mindset that when you point your weapon at a threat, you will be ready to use deadly force. Otherwise, don't pull and point it.
There are several very good threads on this forum that talk about these scenarios. I suggest you take some time to read through many of them. But you also need to know what the TX law says. Read the penal codes that apply to deadly force vs. non deadly force.
Welcome to the forum, and welcome to Texas!
