X8 Slide Action Handgun/sidearm




I believe that this is the first ever slide action handgun to feature a magazine that has been posted on this site. Slide action, true trigger, 7 shot bottom loading magazine capable of rapid fire. the range is anywhere from 20 to 60ft depending on how many rubber bands you use and what type of firing rod you use.

Step 1: Make the Barrel

this is the barrel

Step 2: The Magazine

bottom loading magazine

1. make these
2. connect them like so
3. do this with them, make sure it clicks into place

Step 3: Make the 2nd and Upper Part of the Barrel

make this

the decapitated peices are not required but highly recommended if you dont want your gun to jam, they can be replaced by tan clips

Step 4: The Trigger

1. make these
2. connect like so

Step 5: The Handle

1. make this
2. spread the red connectors out (it helps with connecting them)
3. connect them

Step 6: Connecting Everything and Add Ons

1. this is what you should have so far
2. connect the upper part of the barrel
3. connect the two parts to the magazine
4. make sure it looks like this and the white rods go through
5. add the trigger
6. add the trigger
7. add the handle
8. add 4 black y connectors to the front and add 4 green connectors to the sides of the white connectors like so
9. add 4 orange connectors to the front and back, it should look like this


Step 7: Making the Slide

1. make this
2. make these (the purple one is just the same as the gray one) also one has 3 connectors and one has 4
3. attach them on and add one extra red connector on the side with 4. the side with 4 should be slightly moved back
4. add more red connectors until it looks like this
5. now build this
6. attach that onto the end of the slide
7. add this gray connector
8 add 2 gray rods and thread them through the gray connectors at the side
9. attach the slide to the gun

ok your done with part 2 what do you want a cookie?

Step 8: Firing Pin

very simple, two pieces and some tape
1. firing pin
2. slide firing pin through the slide
3. slide firing pin through barrel

Step 9: Adding Rubber Bands

1. add rubber bands to trigger, do the same on both sides
2. add rubber band to make magazine work
3. connect it to other side
4 add rubber bands to firing pin

Step 10: Loading/firing

1. add in white rods
2. put rubber band through like so
3. slide the slide back

after you slide it back, move it back into place or else it will not work, then just pull the trigger.

you have made this gun, yay cheer woot, now go get yourself a dam cookie

    Meh, its okay -- 3 stars (my magazine didn't work, and my gun only fired two feet with my best rubbabands) I took off the mag, slide, and nearly doubled the length of the barrel, and now it shoots 40 feet accurately

    you know, i used to make tons of knex guns. i've made pretty strong ones and cool mechanisms before (one mechinism allowed the bullet to shoot so strong it went through 2 layers of drywall from 40+ feet) but then it hit me: what's the fun of making guns? now i make ball towers. things that don't harm others.

    Looks good but I almost guarantee you that it would not go pas 40 ft. Not only does it fire white rods which always spin cause they're so short, but the rubber bands would just break the slide action firing mech.
