Practice your concealed handgun presentation (from concealment)…
During a recent demonstration on drawing and moving and shooting I managed to mess up the draw (or presentation if you prefer) not once but twice! Both times I failed to sweep my cover garment far enough out of the way and ended up with a handful of shirt in addition to my handgun.
Not a good thing in an actual confrontation. This is something you need to practice regularly. Consider doing a few practice draws everyday (make sure your handgun is unloaded) when you put it on.
This is obviously something I need to work on!
