My wife doesn't carry anymore, but when she did, she carried a Glock 19, in a dedicated carry purse ("Pistol Packing Mama" is the brand name I beleive). She tried other systems, but always came back to the purse and situational awareness.
(Which is why she doesn't carry anymore. A brain injury has affected her memory and she's afraid she'll set her purse down and forget it, so she doesn't carry anything important in it.)
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
