The Kholster Full Moon is my most recent purchase and I still need to work on the draw from this holster as it takes 50-60 draws before everything runs smoothly but I love the ability to tuck in my shirt.
If you're interested in the Khoslters they do offer a discount to you if you are referred by someone else, so PM me and I can send you my referal code and you will receive 10% off which makes it $40.50 shipped.
If you're interested in seeing or trying one of these out first let me know and we can meet up.
Unfortunately there is no such thing. You can only the the "best for you" holster.
Personally I like the MTAC offered by Comp-Tac. I carry my G19 in it comfortably. Once I carried a 1911 in one all day and was *quite* surprised at how well it managed the extra 'weight'.
