The giant heaved up on his sound right leg and his sound left arm, and flung himself forward, two limbs dangling uselessly.

With a hideously contorted face, Bull swung his left arm in a wide circle for a grip and scooped in Pete Reeve, as the latter sprang back with a cry of horror.
The action swept Pete in and crushed his gun hand and arm against the body of his assailant, paralyzing his only power of attack or defense.
Reeve was carried down to the ground as if beneath the bulk of a mountain.

There was no question of sparing life now.

Pete Reeve began to fight for life.

He wrestled at his gun to tug it free, but found it anchored.
