I have a Kramer horsehide pocket holster for my S&W J-frames and NAA Guardian. Another Kramer pocket holster is in the mail for my Kel-Tec P32.
Yes they are pricey ($78) but IMHO well worth the money. The Kydex facing breaks up the outline of the gun and the horsehide construction makes for a durable and stiff holster. It doesn't take much to pop the holster off the gun when you draw.
HTH!
