If I'm carrying it as a CCW gun, I would choose as an IWB type. Kydex would be my first choice because it's form fitted and doesn't require any thumb break retention device. A molded leather would be my next choice. Both are around $40-$45.
Galco has a nice one that is REALLY concealable. Good choice for Arizona, as most of us don't really dress in layers. The Galco Push Up Inside the Pants holster (Model #PU436) tuckes WAY down in your pants. The barrel is slightly exposed, allowing you to use your finger to push the pistol up above the belt line, so you can grab it.

OpticsPlanet.Com has it for $43.00 delivered.
Of course, you could have a local guy custom make one for you. As Michael and I have experienced, YMMV.
For small pistols, I also favor a pocket carry option. DeSantis makes one called the Nemesis. It's pretty inexpensive and I've heard good things about it. THe outside material "grabs" the inside of the pocket. The interior is padded with a foam core. This makes it comfortable and breaks up the pistol outline. Combined, it makes for a smooth draw holster.
If you wear baggy pants, then it's probably NOT a good option for you, as you may pull your pocket inside-out.

MidwayUSA.Com offers it for $18.00. Although, I would look local, as tax would be cheaper than shipping fees.
Also, there is a guy on
AR15.Com that is selling a slightly used Kydex SharkTac IWB for $20. Nice price!
With all this said, I would personally recommend the Galco. Leather is more comfortable than Kydex. Especially in the summer. Textured leather tends to not shift when you're wearing it. Kydex is smooth and will shift a bit.
Leather absorbs sweat, traps odor, and discolors over time... yuk. However, the PROs outweigh the CONs.
