Check out a Lobo Enhanced Pancake. I've been carrying a variety of J frames in one for years and could not be happier with it.
R. Grizzle is worth the wait and the money, well spent. You won't find a nicer artist. If you go for the Grizzle don't forget to ask about getting your holster lined if you have a gun worth protecting and I assume that is the case or we wouldn't be talking Grizzle. Great guy, fantastic craftsman.I use the Simply Rugged and it works fine. Sits a little low.
My next J-Frame holster will be from R. Grizzle, the High Country holster.
I have this for my S&W autos and find it the best belt holster for me.
It is high and fits close for a Shield and M&P 9C size, it is almost as concealable as inside the waist band with the short barreled Shield.
Here is my Wright Leather Works "Predator". This holster will hold your J Frame snug against your body. The fit and retention are perfect. I also have a Predator for my Shield. Leather Concealed Carry Holsters & Belts | Wright Leather Works LLC
