SilencerCo Maxim 9 Non-NFA

SilencerCo is a manufacturer of firearm suppressors founded in 2008. The Maxim 9 was SilencerCo’s first fully functioning firearm and the world’s first integrally suppressed 9mm handgun that represents one of the greatest strides made in both pistol and suppressor technology. https://silencerco.com/maxim-9

As the Maxim 9 is a silenced weapon, it is carefully regulated in the US by the National Firearms Act (NFA) and, like other silencers, must be licensed. SilencerCo's response has been to develop a regular handgun based on the Maxim 9 template, but without the in-built suppressor. As of April 2020, the SilencerCo Maxim 9 Non-NFA is still in development and has not been released for sale.

This is a non-working prop for display or cosplay purposes; there are no moving parts or insignia. It is not an exact replica, but I have built the model with as much details as can be gathered from first-look internet reviews and videos of the actual handgun.

I'm confident that this is the first and only printable model of the Maxim 9 Non-NFA available. I also have a detailed model of the originally suppressed Maxim 9 available here: https://cults3d.com/en/3d-model/various/silencerco-maxim-9-long-and-short-configuration-colinp_hughes-2

The Maxim 9 Non-NFA has one configuration and is referred to as a silencer-host. For that reason it is expected to operate with a silencer without any special modifications. This model provides the threaded barrel and has an optional fittings to suit: a threaded end cap and a replica of a direct thread SilencerCo Omega 9k suppressor, that can be fitted as desired.

Disclaimer

The model .STL parts and these instructions are provided as is. This is a fan-created prop not affiliated with SilencerCo in any way.

The model has no moving parts. It is designed for display purposes. It can be used for cosplay if suitable precautions are taken such as fitting an orange safety cap to the barrel (model provided). I do not endorse the use of this model as a representation of, or conversion into, a working firearm.

Please observe all local legislation regarding replica (or lookalike) firearms, especially when in public spaces. Remember, a law enforcement officer will not distinguish this from a real weapon and I cannot be held accountable for anything that happens to you!

I split the model into printable parts along natural seams so that it can 'click' together without filling, repairs or special post-processing. All parts are orientated for the best print. Unfortunately some parts will need supports to print successfully in these orientations. Some tips for printing and building follow:

I print all my models with a 0.4mm nozzle and 4x shells (1.6mm) for strength and to provide a thick enough surface for sanding. Print all parts at 0.12mm layer height to maintain details and fitting tolerances. Some parts will need supports. Use your judgement on where these need to be, but note that the frame is tricky and prints upside down with supports, but that morse code grip texture will print perfectly without supports. Personally, I prefer to use a raft whenever using so many on-bed supports. Your mileage may vary.

Infill can be kept to a minimum, however, I prefer my handgun models to have extra weight so I print at 60% infill. The Maxim 0 Non-NFA, like most handguns, is weighted at the back end. My advice is to print the frame and slide at 60% and the barrel at 25% to ensure the correct balance.

All parts should be obvious in the way they fit together as there's only one way, that is with the exception of the magazine; make sure you get it the right way around. Sand all parts and check the fit before gluing together. Think carefully about the order you're building the model in and if parts need to remain unglued to help with painting and finishing. I recommend Super Glue or any other Cyanoacrylate (CA) based equivalent. One with a 10sec or less setting time is especially useful.
