Shush Puppy Suppressor Details
The Shush Puppy is an innovative suppressor design that sets itself apart from previous options on the market. Unlike monolithic designs restricted to smaller caliber ammunition, or baffles that require additional outer tube purchases, this suppressor is modular and 3D printable with a 9mm capability and requires only one purchase of a firearm part- the muzzle device.
Note: Make sure you have the proper paperwork prior to printing the Shush Puppy. Failure to do so could create serious legal consequences.

Shush Puppy Suppressor Tech Specs
The Shush Puppy suppressor design addresses the issue of maintaining DIY suppressors, as technically speaking, maintenance on form 1 suppressors should be handled by SOT/FFL. With Shush Puppy’s modular design, new baffles can be replaced without sending the entire suppressor for maintenance.
The durability of the design has been thoroughly tested, as my personal 9mm version has already fired one thousand rounds over the course of a year. Other testers have also modified the bore to accommodate larger calibers and tested up to 100 rounds with no issues. While it has yet to be tested with rifle rounds, the Shush Puppy’s design has great potential for suppressing 22LR, 9mm, 380, 40, and 45 pistol rounds with a modified bore.
