K'NEX Small Starter Pistol Instructions (SMSP)

Here is a small KNEX starter pistol I made. It is pretty simple, sorta compact, and holds 5 purple/gray connectors in the magazine. Here are some PROS and CONS before we get to the instructions.


-Five round capacity


-True Trigger

-Easy to load

-I guess pretty good range

-Handle magazine (not removable)


-Only one I could find was there's no front sight so you just look down the barrel, but that's no big deal.

Now let's see how to make this awesome little gun!

Step 1: What You Need!

Here are the parts you will need to make the SMSP.

Step 2: Body and Handle/Mag and Trigger

Here is the body and handle/mag

Step 3: Foregrip/Handle Guard

The fore grip/handle guard

Step 4: Rear Sights

The easiest part: the rear sights; two green rods

Step 5: Ram Rod/loading/rubber Bands

Putting on the rubber bands, ram rod, and magazine pusher

Step 6: You're Done!

Now you are done with your SMSP! Now you can shoot something with it!

The foregrip looks pretty uncomfortable, with how little finger room there is. Maybe change the top yellow connectors on it to orange ones? And maybe change the red ones that connect to the handle to 1-slot grey connectors.
The trigger / magazine set up isn't great, with how much energy gets lost by pushing the ammo out of the gun, but that's a problem just about all handle-fed k'nex pistols have.

All in all, it isn't something we've never seen before, but hey, you're a new, active member to this community, so that's definitely cool.

I see what you mean by the little space there is. I never thought of changing them to orange on the handle guard. And the red connectors on the bottom.

Sorry I forgot to mention to load a bullet into the chamber pull the ram back until the bullets in the mag shift up then let the rod back in. Then you pull the trigger to fire(obviously).
