Jason,
The nano-weapons you have are fantastic for easy concealed carry (even what we call "deep" concealment). If you plan to carry, pick a method of carry and practice drawing and dry-firing from your concealed holster, in the place you will carry it. I recommend getting some "snap caps" for dry-fire drills, so you don't damage your firing pin (dry fire is very hard on it).
With that being said, I want to add that you will eventually want to get a bigger pistol. While the nanos are great for a concealed backup, you will soon find that they are very limited at the range, and the "fun factor" will also be limited. They are good at very close ranges - 10 yards is really reaching out for very short-barreled nanos). This weapon is for very close-in, self-defense encounters; no time to draw and aim, just react and fire. As you learn to shoot, you will long for a little more "oomph!" Being able to accurately shoot farther is important, and much more fun! When you get the bug, and the desire for a little more, hit us up for recommendations! (You likely will, by the way).
On the flip side - if you learn the fundamentals of pistol shooting with a very short barrel nano, and get good, transitioning to a full-frame will be a piece of cake!
