The angle of the thumb rest is the same as their thumb rest for open guns. It’s huge and feels like an open guns thumb rest. The ghost hydra holster fits the gun and can be set up for the legal distance. I don’t think I shoot any different with it on vs off.
The metal the pin is made out of should eliminate the issue of slide stops breaking.
Pros: it’s huge, positions your hands like an open gun, the slide stop will not break.
cons: you will need a new holster.
