Introduction: SFP31

Picture of SFP31

This a random new pistol I made. The idea of the mechanism is similar to the concepts in IAC's and TheDunkis's guns, but it's quite different. It holds up to 7 shots, and shoots a bit more than 40 depending on bands and stuff. Only problem I have is a trigger pull that is harder than most guns, but isn't that hard. It's compact and has a low piece count.

Step 1: Pieces

this thing is awesome,while i was building it,the barrel rod shot INTO the couch,this is OP.

I have a question. Can you use blue rods with this gun? The mag part looks wide enough to fit blue rods. Like a knex AK-47 mag would hold blue rods. Please reply ASAP

You probably can, but i think that I used these ammo pieces because they wouldn't get caught on each other. You can try it out though.

 hey i re-found this lil pistol i totaly forgot about it lol time to get bulding 

Lol wow. I completely forgot about it too. I have a much better single shot pistol coming out soon anyways.

It looks ok... But there isn't really anything new. The trigger is semi new, but only based off of TheDunkis' assault pistols.


silentassasin21 (author)travw2009-07-04

its not based because it has a similar trigger and it isnt even based on anyones gun

shadowninja31 (author)travw2009-07-01

It's related in concept. Go look at his oodammo pistol. The trigger is yes, same in concept yup and somewhat close in build. The rest of the gun however is not based on any gun really. But okay I'll accept your rating.

travw (author)shadowninja312009-07-01

Ok, a *3.5* because you were nice about it.

shadowninja31 (author)travw2009-07-01

Lol okay.
