Are you dry-firing without a magazine in the gun?
If the magazine is out, the trigger is disconnected from, and is not moving, the striker. When the magazine is in place, the trigger is moving the striker back against significant spring pressure.

The long, hard trigger pull is a major safety device, in this gun.
The only way to overcome the difficulty you're having with the trigger pull is to exercise your trigger finger, and improve its strength.
There are several devices which will help you to do this. The important issues are twofold: First, you need to exercise the trigger finger. Second, you need to be able to isolate your trigger-finger's pull, to keep it from affecting the grip of your other fingers on the gun's handle.
The device that my wife, Jean, finds most useful for doing this is the Gripmaster, in its Medium version (click on: http://www.prohands.net/products/gripmaster.php). She grips the device with her lower three fingers as if it were a pistol, and then, maintaining that strong grip, she separately presses the index-finger pad of the device.
