Now take the rectangle and select the remaining tip of the handle. Stretch it out for height. Then pull it out for length.
Now, if you haven't noticed, the hand guards are firmly attached to the handle. This limits our details for the trigger guard. What we can do is grab the tip of the upper guard, shrink it, and rotate it 180 along the Z-axis (Red Ribbon/Ball).
Next step is to move it to the bottom, shift the trigger to curve forward, then pull out the bottom guard to form the trigger guard.
Now take that bullet chamber floating up there and move it over the front of the handle.
Now, you can just give up here and just slap the blade back on the handle... or you can do a good job and rework some details into the blade.
First, we need to flatten out that blade a bit so we can work with it more easily. Select a large section of the blade and raise it up to the other half.
Then take these three jagged edges, activate the scale tool, push the Y button (green), enter a 0 in the number box, and hit 'OK' to flatten it out.
