I've got a Remora IWB holster I use to cc a 3 1/2" 1911. My gun is obviously to big to pocket carry, but I think the Remora should be a good holster for pocket carry. Ankle carry is a highly individualized thing. Personally, none of the folks who I know that started off using ankle carry continued it. My style Remora doesn't work well as a "tuckable" holster, although Remora does now have a "tuckable" holster.
Depending on your situation, you may want a holster that is tuckable. There are a bunch of tuckable holsters on the market. I've very pleased w/ my two, a "Lone Wolf-T" from here http://woolfegunleather.com/index.php?main_page=product_info&cPath=3_1&products_id=8 and a "Tuck Clip" from here http://www.sideguardholsters.com/holsters/IWB_Holsters.htm
For a small, light gun like the LC-9, you might want to consider a single clip holster like the "Tuck Clip." Woolfe also makes a single clip holster called the "Wolf-Bite". The single clip holster is as stable as a double clip, but more convenient and easier to put on.
Here's my "Tuck Clip" w/ my Kahr CW45.
