Thank you so much to those of you who weighed in! Looks like I have a lot to consider! I hadn't really thought about going with a single stack gun but it really makes sense!
I have seen the Falia Photography videos. Thank you, she is a wealth of info for women CCW holders. I know I will have to dress around the gun -- I think it will be easier to pull off with a smaller one.
The class I took is called Zombie 101. It's a fun eight hour class where you get really comfortable drawing and shooting. I shot about 200 rounds and really benefitted from the experience.
