Wayne - I either own, or have owned, almost all of the "small" guns listed in this thread.
If you want a NAA .32, get one. It is a very reliable gun and good for its purpose. Remember, the larger calibers are nice, but you are looking for a gun the size of a NAA .32 for a reason. If you can use a larger gun for your purpose, then get one. If you need a gun the size of a NAA .32, it will serve fine.
Don't get hung up on the caliber size. A .32 with proper ammo, such as hydrashok JHP .32, is very effective for your use. Again, remember why you are buying the gun! If you want a small gun, you're not going to carry a .45!!! A lot of what you see in these threads is young testerone talking...I would ignore it and buy the gun that suits your needs.
