Thats the way it was intended to be carried.
Assuming the thumb safety is in good operating condition, and stays on when you put it on?
The very stiffly sprung grip safety precludes the trigger being pulled unless you have the gun in a chicken-choking grip and pull it.
Just be aware the design is nearly 100 years old, and doesn't include modern firing pin lock drop safeties and such.
So, you should probably make a habit of not dropping it.
