You can buy the shell only.
To say that I am a pretty big feller is an understatement. I tend to sweat setting still in the shade. Of course the holster does heat things up a bit but it's not really noticeable until you take it off.
There is no noticeable wear on the holster due to moisture...
Add me to the fan club!
I have the 2.0 with shells for my G23 & G41 and can't find an issue with either.
Comfortable, durable and holds the gun in place.
