How important is it? I don't know, how much do you value your life? Trans or not, I am an advocate for the second amendment.
I frequently conceal carry my Glock pistol on my waist. I advise against carrying in a purse as many criminals prefer to "purse snatch" as opposed to an actual "give me your purse" type incident. Furthermore, carrying in a purse is not exactly readily accessible. I have never had to fire my weapon, however, I have had to draw it. There is very little time to draw your weapon, and typically if the assailant is within 21 feet, you will not have your gun out in time to successfully use it; at that point, you're better off running or engaging in hand to hand combat.
