You'll definitely see reports Stan and I agree that it's kinda just all around a fun concept...

I don't know how much, if at all, you follow the gun 3d printing stuff but it has went from 0-60 faster than most people thought was possible. Let me introduce you to the FGC-9 if you haven't seen it yet.

This is the FGC-9 in all it's Glory and in many ways these are what really pushed me to starting my project. There are people making these fully from scratch right down to making the springs themselves and using 3d printed bath tub ECM rifling equipment to do the barrels.

As you can kinda see in the parts layout picture, the fgc-9 is more or less a pp-2000 with the bolt flipped the other direction.

It made me realize that rather than lamenting that nothing commercially available ticks all the boxes to make a good cheek pistol, I should just make my own damn cheek pistol that fits what I think would be best!

I had a really rough 5 year period that cost me my health and the majority of my tools etc and in some ways killed my enthusiasm for actually making things, but the cheek pistol concept came along and I realized that I could probably actually build something worthwhile if I just put a couple grand into tools and got to work.

And that's exactly what I'm doing. It's going to force me to make my own tools to make the gun which Ultimately benefits me too!

In the post above this I outlined my initial approach to gatnerd but you all can rest assured that I have a whole laundry list full of interesting gun ideas I've dug up over the years which will likely make appearances in various iterations of the two basic guns. I'll be documenting what I do and how I do it as this project gets rolling, and I'll definitely make sure you guys can follow along.

Glock mag MAC- doesn't Masterpiece Arms make one of those now?

At one point you realize Styer TMP is just about the smallest form factor you can get , and rigid side folder bunch better support than flimsy telescoping stock ,

While conventinal SBR like SIG Rattler are pushing close to  Mp7 size, the pistol like holsterable gun is preferable way to carry , but at 2kg MP7 ist a bit heavy for what is is. Folks have built full sized ultra light AR15s under that weight

"Glock mag MAC- doesn't Masterpiece Arms make one of those now?"

They do indeed. Amusingly, their MAC barrels are all made on the same exact barrel tooling as their competition winning Precision Rifles. 

The result is these little Ghetto Blasters are shockingly accurate. I've got the MPA 5.7 MAC, its a 1" @ 25yd gun.

They do, but they're almost $700 each.

Whereas I can likely find what I need for about $300 any of a couple places which basically boils down to a top cocker m11/9 parts kit or parts thereof and then "print a lower" similar to this but with a mag thru grip layout.

What I'm thinking of is a minimum 5.5" bbl with an OD and thread pitch etc compatible with an appropriate linear comp or modded "blast can" with a brake inside and constructed in such a way that I can swap out bottom assemblies relatively painlessly. (Likely an adventure all on it's own)

It's a good starting point and a safe launching pad to work from so that I can start changing things from a "known good" reference point, and frankly I can afford to break parts like this trying stuff. 

There's also metric shit tons of already known good 3d printable parts for something in this particular vein. The Mac upper probably isn't the most ideal starting point being a little large for the hand wrap stance of the cheek pistol when ideally you want an mp9/mp380/b&t usw size body.

There's lots of suboptimal things about the initial design including potentially even the fcg etc since we need this to have a decently usable trigger to work.

But there's enough room inside something like this to work and try things out.

Once I get internals and stuff sorted and everything working the way I want I'll finish one in the modified almara configuration I'm working on just to keep and to play with. 

I have lots of ideas for stuff to change and by the time I'm finished it probably won't be anything resembling the original gun and that's the fun part if you ask me.

I've been gathering up old George kellgren proposals and uziel gal stuff etc because I'm definitely not ashamed to copy something that works.

Yup lol, I'm hoping I can find a masterpiece arms barrel to put in some of my initial monstrosities...

Sorta not looking forward to sourcing or doing my own 22 tcm barrel from a blank if it comes to that but oh man will the results be worth it if I can make something that works half decent!

I also have some interesting ideas on potential operating systems that'll have to wait until further in to try too...

Suffice it to say that I intend to leave less stones unturned by the end of this

Their MP 380 is also definitely an inspiration of mine along with some early kellgren guns.

I consider myself lucky In that respect because there's All kinds of phenomenal ideas that I just need to aggregate and put into a single gun.

Not as exciting or cool as designing something completely from scratch but still a task worth doing.

My new 3d printer and some parts for my other machines arrive between this Friday and next. It'll probably be another 2 weeks to a month after that of assembly, debugging, and workup then the fun can really start.

If it's ok with you I'll just use this topic as my build log etc.

That sounds great to me. 3D printing is a cool and emerging firearms tech, especially for rapid prototyping, so I think having members here printing gats would be well in keeping with the overall discussion of current and emerging small arms. Not to mention, just being cool as hell ;-)

Yeah, I agree.

3d printing is far from a panacea but it has it's uses for this stuff
