A leather lined kydex holster of good quality is going to be bulky and expensive.
What's your reason for such a holster? Respect personal preference of course.
Is it wear against the slide?
It was/is for me with all holsters which is why I make my own.
I use .080 kydex and allow a noticeable gap all the way around the slide so that it never touches any part of the slide even when inserting/removing the firearm as it clamshells around it which pushes the kydex away while it's transitioning direction. I've laid on my side many... many times (it's my EDC) for well over a year and there's not a mark on it.
I also installed a 1/8" thick piece of leather on the side that presses against me for comfort.
I can and do wear it all day, everyday as it's that comfortable.
Another plus is I have maybe $20 into it.
Try making them yourself, all that's needed is a heat gun, the materials, some patience, and to be willing to make a mistake or two when you first start out.
After you get it down though, you'll probably never buy another holster again.
I've added another photo of one that I made for when I'm wearing shorts. I use a speed belt and the 2nd holster and it rides just below the waist band of a snug, drawstring pair of shorts.
Not so snug that I can't get to it quickly. The pull-the-dot softloops stay in place as they can't come off the thin belt. This one doesn't have/need the leather backing because it doesn't press against me near as much as a pair of jeans with a gun belt.
Just giving ideas.
