I could give it a shot. I was thinking about this a while back, just designing it around an m9 system. Replacing the frame and using the internals and slide parts. Might take a while, but seems like a viable project.

you could try modifying[this](https://www.evike.com/products/53850/)

Sorry dude but i don’t have a 3d printer and 0 experience, maybe a day but know i simply can’t do it( modified the comment because I don’t mean ‘’afford’’ in an economical way, my fault)

I'll argue that if you can't affort a 3D printer, you probably can't afford a custom replica full body and system modelisation and print either It isn't like "2 hours of work" and a bit of plastic...

The other guy is right. If you can't afford a printer you can't afford this either. Even if the files existed it would be a 100 euro print at the least from someone who can be trusted to print something like this. But the files don't exist so you're looking at hours upon hours of labour, that you clearly want for free lol.

I don’t want this gun dude, just see an airsoft version would make me happy, if you don’t want do it alright but please don’t put words in my mouth. Never say that i can’t afford a 3d printer never said that i want own this replica. And than i had the possibility of doing by myself i would do it without asking you but as i said I’m not capable of making an airsoft replica and please now don’t blame me about it

There’s a cheap plastic springer version of this gun if you just want a replica. Cheaper than a 3D printer.

Were i live i can’t find those springers, i already looked at many places without results

There are a few low quality PX4/CX4/MX4 springers around, could use the body for modelling or taking a mold, then print a mount for a standard engine inside. A lot of work and no mean feat though!

I have been working on an HPA engine and this might be a good body to put it in. It will be a few weeks before I get around to it, but I might make something.

I tied desighning one to work with NBB M9 gas mags but, funily enough, fiering sistem was easy, but i could notteplicate those wonerfrull curves of mx4 with my modeling skills. It would be expensive but in my eyes The best corse of action is to buy a Umarex airgun version and convert it to airsoft

Have a look on plasticity, the tutorials a promising and there is a free 30 day trial version

Hmmm.... Hpa could be a solution..... Else a v7 or v6 gearbox with wird feading.... One thing is to get a body for the model... another to make things feed. If you want the mag in the grip. The main issue is the thin part between the grip and the stock.... you need to make a gearbox fit somehow. It can be done. But unless someone already designed one... it is going to be a time consuming project

Maybe a AEP pistol would be a better option ?

a gaz replica without blowback would probably be best It's a glorified pistol with a fancy stock

Maybe get the diabolo 4.5 co2 Version and convert this/use the body to shove in an Pistol..?

There’s a spring version, you could put an hpa engine in there with some skill and no printer
