This is what I used with a G26 for over a year and the J-hook is not really that noticeable if you use a black belt. It's extremely lightweight, well constructed and easy to put on/take off. The J-hook is not as 'obvious' as others I've used.

I do feel the need to mention this though: folks who carry and have used J-hook type holster before will probably notice it and they will know what it is...
