I agree with others that you will likely end up with a number of holsters before too long. No matter how much you research and no matter how many opinions you get about a particular holster being fabulous, one size does not fit all, and what works great for someone else may be terrible for you. You won't know for sure if a holster works well until you carry it for a while.
The next issue is that you will likely need to use more than one concealed carry style depending upon the dress required for your activity, whether it's wearing a tuxedo for a fancy event, or wearing jeans or cargo pants to the grocery store. It will take some trial and error to figure out which carry methods work best for you. This will likely mean at least 2 or 3 holsters to work with your carry needs.
Yet another issue is that you may need to modify an existing holster for your particular carry needs.
Example 1: I extended the magazine release button on my pistol. Unfortunately, my pistol no longer fit into the holster. But I was able to cut a 1" long slit into the holster, heat up that section and slightly reform it to clear the extended mag release button, and then heat weld the slit of the reformed section back together with a soldering iron. Now it works great and it still protects the mag release button from accidental actuation.
Example 2: I bought a $20 DeSantis Nemesis pocket holster. It protected the trigger well and held the pistol upright for easy draw from my pocket.
However, it printed badly. But the $20 that I spent was well worth the money, as I was able to determine that pocket carry was a viable option for me.
A cheap and dirty temporary solution for the printing problem was to place a piece of scrap leather in front of the pistol to stop the printing. A more permanent dirt cheap solution would be to sew or glue a piece of scrap leather onto the front of the DeSantis holster to stop the printing.
Example 3: In this case it was my pistol that needed modification. In order to better fit my pocket holsters I cut off the manual trigger safety lever from the right side of my pistol. You can see this in the photo above inside the DeSantis pocket holster. Being right handed I had no need to use the safety lever on the right side and it was a protrusion that didn't need to be there. In a pinch if I need to shoot left handed, I can still actuate the safety lever on the left side using either my left thumb or left index finger.
Example 4: I eventually chose to spend a little more money and bought a horsehide Recluse clamshell pocket holster. HOWEVER, the pocket holster would NOT open wide enough for my extra long fingers to reach inside and get a good grip on my pistol. I had to remove some stitching and restitch about 1.5" lower and now it works great. Also note the holes that I punched into the holster to improve the ventilation. Horsehide is often preferred for inside the pants carry because it is more moisture resistant.
Example 5: When I bicycle in the summer, the only carry method that works well for me is a fanny pack worn to the rear. I couldn't find any fanny packs that suited my needs. So I made a fanny pack and modified an existing holster and mounted it inside the fanny pack. After a bit of trial and error and quite a few design changes it now works extremely well for me.
Example 6: This wasn't a modification, but instead making my own magazine holster for my rear pocket because nobody was making one with the magazine offset to one side to make it easy to sit. I went through a lot of trial and error, but this holster now works very well. I punched holes into the leather improve ventilation, to reduce the condensation, which helped a lot. I made this holster from scrap cowhide. But I will be remaking this from horsehide and having a flap that extends the length of the magazine to prevent the condensation on the magazine.
Consider holster modifications somewhat akin to having your clothing tailored for better fit.
I am NOT suggesting that anything that I have done is right for you. These are just examples of possibilities that worked for me. But if a holster isn't working quite right for you, try to figure out what the problems are. When you know what the problems are, maybe you can make a small change to the holster to remedy the problems. Maybe you can then find a holster to do exactly what you need. Or maybe you can have someone custom make a holster that will do exactly what you want it to do. Or maybe you will get very lucky and find the perfect holster on the first try. Holsters are a learning experience.
