This is a very accurate moderately powerful non-semi-automatic hand gun. It has no magazine so you have to load it for every shot. Still, i think it looks cool and its very accurate with the scope on.

You'll need,

8 White Snowflake Connectors
4 Blue 3D Connectors
20 Green Connectors
9 Yellow Connectors
8 Red Connectors
5 Grey 2-Slot Connectors
6 Grey 1-Slot Connectors
8 Orange Connectors
28 White Rods
7 Blue Rods
12 Yellow Rods
36 Green Rods
4 Y-Connectors
2 Tires
1 Small Gear
2 Rubber Bands

*If someone could tell or show me how to add a magazine that would be great...
**You can tell me if it sux but don't be like "Wtf, there r 2 many knex gunz on the webz, stop making them!!!!111!!1!1"

Step 1: The Main Part of the Gun

This is where the rods are loaded and fired once the gun's done.

1.) Make these.
2.) Attach them with these rods.
3.) Here's another view.
4.) Make this.
5.) Attach the blue rod to the blue 3D snowflake connector.

Step 2: The Bottom of the Gun

Technically you don't need this part but it makes the gun look cooler.

1.) Make these.
2.) Make this.
3.) Connect it all together.

Step 3: The Trigger

The trigger locks the firing pen into place when you cock the gun. It won't be able to withstand too much pressure.

Not much explaining to do.

Step 4: Connecting the Bottom of the Gun to the Top

Do it!

Step 5: The Handle

It took me a while to construct the handle. Its very comfortable though.

1.) Assemble these parts together.
2.) Connect these two sides together.
3.) Clip together the two orange connectors.
4.) Attach this blue rod through these two holes and then put the orange connector on.
5.) Put these on the sides to make the handle wider.
6.) Attach this yellow rod on.
7.) Put these green connectors on the yellow rod so they face like this.

Step 6: The Firing Pen

Shouldn't be too hard.

1.) Put this together.
2.) Slide it into the gun. You might need to pull the trigger to make it so it fits in.
3.) Put a Y connector onto a blue rod. Yes, you need this.
4.) Attach it on-top.
5.) Add this blue rod.
6.) Slide a rubber band through the hole of the red connector and hook it over the blue rods.
7.) Put a rubber band on your trigger.
8.) This is what your gun should look like.

Step 7: The Scope

This is optional. I think it looks cooler with it on.

1.) It might be hard to get the yellow rods on all 8 sides of the white snowflake connector but do your best to.
2.) Slide on two tires.
3.) Slide on two gray 1-slot connectors so they're 2 yellow rods apart.
4.) Put these on.
5.) Fit a small gear into the yellow rods.
6.) Put two Y connectors onto this blue rod.
7.) Attach the scope here,
8.) and here.
9.) W00t, 1337 Pwnage! Go kill sum1!!!!!! (jk)

Step 8: Loading and Firing

This isn't semi-automatic or whatever so you have to load it for each shot.

1.) Pull back the Firing Pen so the trigger locks it into place.
2.) This is your ammo.
3.) Place a rod here.
4.) Pull the trigger. U needed explaining 4 that?
