I am so awesome. After I finished up on the range, I went into the shop to browse through the holsters. I've been making do with the removable holster from my concealed carry purse, but it can't be used for inside-the-pants carry. I managed to find one that fits my Glock perfectly. I love it so much, I took pictures.
Wow, I'm pale. Those are my new capri workout pants. I was worried that the holster would pull them down, but it actually doesn't all that much. I think I could walk with it on those pants without too much trouble. And, you can't even tell that I'm carrying a gun under my t-shirt. So, problem solved. No more fear of meth-heads in the arroyos terrifying me while I'm out on a walk with Ferguson. I will shoot their asses.
