I got nothing
Well, everything is going to wear eventually... but I should expect a Kydex holster to last a loooooooooooong time.
What type is it? Can you show some pictures?
Here is the big one... is it hot where you live and do you leave the holster in your car?
No pics of it at the moment but it is this one

Miami is very hot and I do leave it locked in my car during my work day.
Don't get me wrong, I'm not bashing but was curious if this was normal. While worn, it's not noticeable.
The Kydex can be heated (heat gun, hair dryer) in the trigger area then slightly push in on the warm Kydex to increase retention. If you send the holster in this is what the manufacturer will do.
