Here's my latest holster. It's for my winter carry Smith & Wesson 469. I followed the same pattern as my AIWB I did for my Sig P239 with a couple improvements.
I thickened the rear section that supports the grip end and widened both J-hooks to improve on durability. I maintained the curve to the clips I used on the Sig holster which helps with allowing the holster to bend with my waistline. The holster is easy on/off and is surprisingly comfortable. It holds the gun securely until I need to draw it which it does quickly.
The Smith & Wesson 469 is a double stack so it's not a thin gun. With a t-shirt draped over it's still noticeable that there's a lump, but it could easily pass for a cell phone and in no way looks like a gun. Here's a short little video I made that shows how easily it comes on and off and how it conceals.
