I'll put my .02 for what it's worth! Be warned, I'm super new at carrying! I like the appendix carry personally. I'm constantly bending over and my clothes always get hung up my gun when it's in the typical 3-5:00 position. It's generally the worst when I'm buckling the kids in their car seats. Imagine the stampede of mommy
when they spot me printing. NOT cool.
I like that the gun is easily within reach at the 1-2:00 position. It's also easier to carry my son on my hip since he doesn't have to be touching the gun. If I had to pull it from the 3-5:00 position, I'd be concerned I would hit one of my kids before I had it up to shoot, as they are young. With the 1-2:00 position, it's right there. For me, the appendix carry is in "my space", whereas the kidney carry, is more behind me, out of "my space", and I just feel more vulnerable with it back there. Maybe I'm not wearing it right at the 3-5:00 position! Who knows.
I typically wear untucked blouses/sweaters so the iwb appendix carry conceals well for me. If I do happen to be wearing something the prints easier, I can always maneuver myself to keep it from printing, or keep whatever I'm carrying right there for the time being. I do not like when the gun rubs against my skin, so I try to wear a cami under a regular shirt/sweater. It has been pretty easy to conceal since it's cold, but I imagine, I'll have to either invest in another holster or get some new clothes for warmer weather (oh darn!)
Oh, and the holster I use is a high noon. It was the split decision, but I took it apart, and basically turned it into the Hidden Ally. I *highly* recommend trying that holster. It has a NO cant, so it's nice and straight... no rib poking.
I am still struggling with keeping the gun closer to my body. When I sit, the butt will often jut out a little. I haven't figured out if I really do need a belt or it's my belly.
I suppose it could be my pants too. I have found that I can carry comfortably in some pants and not others. Those with slightly higher waists are totally out for me.
If your wife wants some pics, I will try to take some this evening or tomorrow and post or pm them to you.
I'm glad she is more interested in carrying on her person now!
