The Tuna Cans SLIM9 delivers the same ultra-compact footprint and lightweight handling you expect from the Tuna Cans lineup—now in a 9mm configuration with a .399 bore. Machined from 7075 aluminum and built around a 5-baffle K-style baffle stack, the SLIM9 stays extremely light while remaining durable and easy to maintain.
 
Its fully modular, removable baffle design makes cleaning straightforward, and at just 3 inches long and 2.5 oz, it’s a great choice for compact builds where balance matters.
 
No piston/booster required: The SLIM9 is designed to run on pistols without a piston booster (Nielsen device), simplifying your setup and reducing extra parts but can also run full auto on any PCC/SMG.
 
Backed by a limited lifetime warranty, the SLIM9 is built to perform and built to last.
