I like the hybrid holster as it gives the most stable carry for the most consecutive hours.
There are limits for me, especially with the grip height. Though trial and error, I found a grip height that is 4.75" or less is my maximum and width and barrel length were much less of a factor. I'd guess that these numbers will vary based on body type.
So far I have this style of holster for something as small as an XDS to as large as a double stack MP9c and the XDM 45 compact. These all carry great for me, but to get there I had to experiment with several small changes to the ride height, the cant and the position on the belt. For me I ended up positioning it on the belt where the gun's rear sight lines up with the outside seam of my jeans. Speaking of belts, you are using a gun belt, right?
If the current position is not working for you, try adjusting it again. Once you find the sweet spot, it will feel most comfortable. Until you find it, it will be uncomfortable to some varying degree.
If you have tried to make it work and it still is not working for you, then send it back for a refund and try something else. Even a change in brand in this style can make a difference. While they generally look the same there can be subtle differences in their layout and implementation.
