Introduction: Knex FX-9 Pistol V1.2

Here it is my new, long awaited, (not really) FX-9 Pistol. I know that it is smaller than my other guns but I had to start somewhere. This is my favorite pistol I have made. It has a good range, Hidden storage, and a safety . Now I now that there is really no use for it but the point of it is to make the gun more realistic. I will be making a version 1.3 later. Be sure to watch the video. It shows the secret storage, safety, and how it shoots.
Here are the facts:
Has a 7 round handle fed mag
Has a hidden storage for a sniper round.
Has a good range
Has safety
It is very comfortable

Does it sound good?? Let's start.

Step 1: Part Count

It's terrible when you are almost done with a gun and don't have enough parts. So I added a piece count.

White 12
Yellow 12
Green 8
Red 7
Light Gray 2
Orange 15 ( one needs to have one tab cut off) if you don't the gun will jam more.

Black / Gray 1
Yellow 1
Blue 9
White 15
Green 55

Gray 13
Blue 4
Tan 10

Odds & Ends:
Ball Joints 5 ( all can be replaced one is on the firing pin and can be a orange connector and the rest can be gray clips. But you will need a rubber band.
Black Hands 16
Rubber bands

Step 2: Ammo Storage

This is going to be the hidden storage.

Pic 1: build 2
Pic 2: build
Pic 3: add white rods
Pic 4: slide over the white rods
Pic 5: add second side
Pic 6: add a black hand to a hinge
Pic 7: add white rod
Pic 8: add hinge

That wasn't that hard
Lets go to the next step

Step 3: Handle

Here is the handle.

Pic 1: build 2 of each
Pic 2: build both. Here is where that cut piece comes it play.
Pic 3: add white rods
Pic 4: add both sides
Pic 5: add the other panels
Pic 6: slant and add black hands
Pic 7: build both
Pic 8: build both
Pic 9: add on each side of the handle
Pic 10: add green connectors

Onto the barrel.

Step 4: Barrel

Okay here are the parts for the barrel

Pic 1: Build both
Pic 2: Build
Pic 3: Build
Pic 4: Build both

Step 5: Check

Okay this is what you should have built.

Step 6: Construct the Barrel

Okay I hope this is not going to be too hard.

Pic 1: build both
Pic 2: add blue rods
Pic 3: add these diffrent parts (don't forget the spacers)
Pic 4: add the second side
Pic 5: add blue rods on the handle
Pic 6: now add the barrel to the handle
Pic 7: now add the third and forth side panels

Great now you are almost done.

Step 7: Put It All Together

We are almost there.

Pic 1: Add the rails
Pic 2: Add the flip top
Pic 3: Build the trigger
Pic 4: add trigger and gray clip.
Pic 5: build both
Pic 6: add ram and rubber bands like so
Pic 7: add tan clips to the blue rods if you want

Step 8: Loading and Firing

Pic 1: Load bullets into the mag like so
Pic 2: add mag pusher and rubber band
Now when you are ready to use slide the orange connector back pull the ram back and pull the trigger.

Credit goes to Trauts for the basic handle design.

Have fun. watch the video. Rate and comment.

Anyway not to use the purple connectors? I have like 15 but this one is for my friend as a present for the holidays. So I would lose them, and only have like 11.

what's a purple connector? And btw you just gave me an idea for a christmas present! :) 


a purple connecter is this=)

Furloy made it! (author)Furloy2010-07-11

to me it would be a bad present. the fun for me is making it, studying it and finding out how to make it better, mod it shoot it a few times, then take it apart and make something else. if you wanted to do something like that, you should give him/her the parts and instructions. just my opinion. btw great gun!

Seleziona made it! (author)Seleziona2010-07-11

I see... But I didn't really like this. It didn't have much power.

Pizzapie500 made it! (author)Pizzapie5002009-12-06

Um I ment the blueish purplish connector. It's like a Tan clip without the little nub sticking out the top. Btw I didn't like this gun very much so you might not want to give it as a present. I decided not to because this gun jams so much and I wasted a orange connector since he said to cut it off. This gun is a 3* ish.

Seleziona made it! (author)Seleziona2009-12-06

this gun is 5-ish! And it only jammed once for me! and i loaded it wrong!

Pizzapie500 made it! (author)2009-12-05

Wait it has a safety? Also whats the top barrel for?


the safety is in the red circle. see? or it is in the center of the picture


The top barrel is for extra ammo pizzapie500

I made it! it is really hard to load and it jams a little bit but other than that it works great!

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-11-26

Oh ok.

The Sensei made it! (author)2009-09-14

I find that using a gray 2-point connector works better for the mag pusher than the 3-point connector.

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-10-24

It could. I don't have it anymore but I could see that working.

knex_mepalm made it! (author)2009-07-11

What do you mean by hidden storage?

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-07-12

You can hide a yellow rod for mepain's sniper rifle in the top of the gun. but if you don't have a sniper it's useless.

Sandy44444 made it! (author)Sandy444442009-09-06

lots of guns shoot yellow rods and u can just store more gray cllips

knex shooter made it! (author)knex shooter2009-07-30

THATS GOOD i modded a rifle and made it shoot yellow rods and this so happens to hide yellow rods btw sounds powerfull whats the range onit

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-07-30

A good 30 feet.

knex_mepalm made it! (author)knex_mepalm2009-07-12

so extra ammo for your primary gun? Wow, to be that desperate you'd have to be that accurate and have a same reaction as me to kill someone close to you.

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-07-13

The extra ammo is for the primary gun. After I built the barrel I added some bulk to the top of the gun for looks, but I found that you can store a yellow rod inside. I know it's not that useful but it gives it some meaning.

knex_mepalm made it! (author)knex_mepalm2009-07-14

ONE yellow rod isn't much meaning for wasting pieces.

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-07-14

You are correct. But I originally didn't make it to store a rod. I just found that it has that capability.

knex_mepalm made it! (author)knex_mepalm2009-07-19

Is it capable of storing more than one? after all, it is your gun and i want to build it but want all the facts first...

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-07-19

Check out my new gun.

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-07-19

No, But remember this was my first pistol.

Sandy44444 made it! (author)2009-09-06

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-08-30

First off use the REPLY button. Second you could use them but it won't look the same.

stopanator made it! (author)stopanator2009-08-31

stopanator made it! (author)2009-08-29

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-08-29

Yes it does. Picture by chance?? I'll help you get it correct.

stopanator made it! (author)2009-08-29

how can you? its impossible

Killer~SafeCracker made it! (author)Killer~SafeCracker2009-08-29

what's impossible??

Killer~SafeCracker made it! (author)2009-08-08

Cool man. I really like it. If I still had the gun I would try this. You might want to do one thing and put a link on the youtube page to this gun so others can build it. But the slide is great. good job.

Killer~SafeCracker made it! (author)2009-08-08

I have seen this ible at 666, 777 and 888. How do I do that??

Killer~SafeCracker made it! (author)2009-08-08
