DeSantis Apache for me; it will fit a lot of different guns.
Whatever you get, be sure it has a comfortable and wide padding between you and the holster. I also recommend being sure the calf strap is removable. I don't use one at all and def recommend trying it with and without one.
Ankle carry is a lot like shoulder carry; it looks easy, but it's not. I recommend trying it full-time for at least a week. If you can borrow a rig and try it out before you commit funds, I'd do that. And, ditch the skinny jeans !
Additionally, try it carrying the weapon on the inside of the weak side leg or the outside of the strong side leg. Both work, it just depends on what works best for you.
Also, we spend a lot of our life sitting down ( restaurants, offices, cars, airplanes, theaters, etc...). Ankle carry is truly the slowest carry you'll ever try to present from, not to mention the loss of mobility as you try to access the weapon from a standing position. If you're sitting, I recommend bringing the ankle to the hand not the other way. Then, practice shooting while sitting if you never have. I'd recommend not training to automatically return to a standing position after you draw, but engage from a kneeling position or a quick move to cover before engaging at all.
You will need to adjust your firearm to ankle carry; something too long snags on the pants leg as you try to draw and something too heavy swings around on your ankle and makes you limp like Festus. J-frames are great for this carry method.
Additionally, retention becomes of huge importance while ankle carrying. We bump things with our calves and ankles all the time and never notice it. I've personally watched a j-frame fly through the air during a foot chase after it was unsecured from an ankle rig. So be sure your holster has a good retention system and you check it often while the weapon is holstered.
Printing ? Nobody looks at an ankle except for a cop or a criminal. Don't sweat it.
Please don't take this as a slam or deterrent to ankle carry. It works. I just want to give you the info I've gathered in thirty years of daily carry, on and off the job. If it shortens your learning curve or keeps you from wasting money on a rig you hate, I've done what I set out to do.
Just my two cents (before taxes) from a guy who's done it before.
