DeSantis has just brought a new pocket holster to market. The ad copy states that its exterior is made of a material that tend to "stick" in the pocket, thus lessening the chances of drawing the gun AND holster. MSRP is $15, so it won't cost much to try it out.
Matt, I have a Pocketlite Mustang, and found several very good holsters:
For pocket carry I have an Aker Express, #155 (http://www.akerleather.com/ch9.html/) it has a flat cover to break the outline and it looks like a wallet in your front pocket.
And for general IWB I use an Alessi Talon Clip. http://www.rfholsters.com/rfholsters/dept.asp?dept%5Fid=10 This conceals very well and the clip is the best I have seen. It will grip the top of your pants and holds on through the draw, without a belt. However, when you put a belt on over it the clip is neatly hidden. It also comes standard with the leather extension. I find it very easy to blouse a tucked in shirt over it and no one notices it.
I also have an Alessi ankle rig that works very well.
You are better off getting a pocket holster from Alessi It is only about ten more dollarsthan the Aker thru RF's, the quality of the Alessi's is ten times better and will last a lot longer ,I got both.
