I bow to your superior knowledge of Texas criminal statutes. My point remains, that an accidental exposure of your weapon is not likely to be viewed as a threat by most people. That does not mean all people will be as tolerant. All it takes is one person who sees the weapon you should be concealing and feels threatened by it, to create a situation that bodes nothing but ill for you.

This is another situation in which the violation is in the eye of the beholder.
If you were to briefly expose your weapon accidentally, while bending over for example. It might be a technical violation of the brandishing law, but it is unlikely to attract much attention under most circumstances. That is not to say that some individual might not freak out for having glimpsed such a weapon of destruction. Brandishing was (IMHO)intended to cover somebody waving a weapon around or exposing it in a threatening manner, even if they did not point it at another person. Most folks I have dealt with seem to agree.
This does not relieve you as a CHL holder from the responsibility to conceal your weapon. If you find that your vest/shirt/jacket rides up and shows your weapon during your normal activities, I would suggest you find another tailor, or carry your weapon differently. On the other hand, I expect that folks sometimes can see a lump on my hip on occasion. So long as they cannot see the pistol or really discern the shape as a pistol, I figure it is "concealed from common view". I have had my suit coat tailored to cover.
