Default Home Made 3d printed guns anyone?

Hey Calguns
I love building things and I love guns. So one would naturally think that I would love to build my own firearm. Unfortunately I live in california, and there are so many laws that obstruct its citizens from making their own guns (it's like they don't want me to do it or something). But if there's a will there's a way (legally). So I started to do some reading and because california has yet to employ an all out band, there are some holes you can jump through.

I started with the whole "have to serialize the receiver" thing. Well ok I'll use an existing receiver. options? Beretta APX or Sig p320. Since the p320 was adopted by the army, I figured that was a better investment.

Now I have to get a p320. unfortunately not on the handgun roster. oh, look a hole(jump), thank you calguns Marketplace. I overpaid but beggars can't be chooser.

I won't go into the detail of the programs and 3d printer specifics (unless you want me to), but there was a steep learning curve. Which is fine this is a hobby after all and it's all for fun.

My first task was to make a exact copy of the p320 frame. Which was easy enough as someone had already posted a p250 frame online and with some slight modifications made it fit the p320 chassis. After printing it and test firing it, I was confident that I could now make custom frames of my own design.

My brother forgot to put on ear-pro.


So what to make? I had two requirements: 1) it had to work 2) it has to be retarded.

I was thinking this:

This is what I came up with:

This is the printing process:

The finish result:

Does is work? IDK I haven't tried it yet. But when I do I will be firing Streak Visual Ammunition. and I still need to put a laser on it, for reasons.

I'll update this thread when I get to go to the range.

My next challenge: 3d printing an ar lower (legally of course). I'm thinking taking a broken ar lower (or breaking one) and replacing the broken parts with 3d printed parts (is that legal? back to the law books I guess).

If you have any questions or suggestions (or you have a broken AR lower) let me know.

The links don't work.

Sounds like a neat project though.

SLA? PET? PLA? ABS? Nylon? What are you working with?

I used ic3d ABS filament. Originally I printed an ABS model to just test the fit. The final model was going to be made of Black PRO Series Nylon Filament. But I decided to test fire the ABS one. And surprisingly it held up pretty well. I do plan on making an Nylon frame since that is the strongest material I can use but for now I'll keep using ABS as it is cheaper.

How do you embed the mandatory 3.7 ounce stainless plate in your ghost gun? Do you add on to plate in some fashion? Apply for serial number for firearm from cadoj then engrave and build around it?

The p320 chassis and the slide take care of all those requirements. The chassis is registered (the part that's considered the firearm) and serialized, I didn't post it because I don't want my serial number floating around the interwebs, but like the stock frame it has a window were you can see the serial number. The slide is a stock slide which far exceeds the 3.7 requirement. Also I resent the term ghost gun, I prefer the term Sooookey gun.

Does the frame have a single piece of stainless 3.7 ounces? Is slide separate? Not familiar with p320. Oh well single shot only so a lot of work for a single shot firearm.

This goes fully semi automatic baby! In all seriousness can someone tell me if the links works. edgerly779 can you see the test-firing video I posted? I really want you to see this thing.

Only the frame is considered the firearm. That is where the serial # plate must go.

And in Ca single shot only. Who cares about a ghost gun elsewhere. I serialized mine before the deadline.Cyrax said built in ca.

Doesn't look to me like you built anything. You took an existing fire control unit and slide and dropped those into what looks like an ND waiting to happen, that you 3D printed.

I'm not too sure that your claim that the serial number on the slide or fire control unit take's care of the requirement for the 3.7 oz stainless plate embedded in or attached to the frame.

It seems a couple of people don't understand how the P320 works.

The serialized part is the fire control unit. That metal piece that contains the trigger is the "gun." What the OP 3D printed is considered the grip unit.

If you own the serialized part, you can change out the grip and slide as much as you want. The fire control unit can be dropped into a full size, compact, and sub-compact grip/slide kit.

Now, there's an idea. I don't know about 3D printers, but can you take a chunk of metal and 3D print onto and around it, thus embedding the legally required metal for creating a home made gun in CA?

photobucket makes some of these really low quality.

That said, this is neat. I figure it's part of the printing waste material, but I like how one of them almost looks like a paintball marker with that big trigger guard.

It'd be interesting to see how the frame handles the stress of firing, and what you can do to toughen it up. Maybe metal reinforcements somewhere?

Let us know how it handles!
