The 16.6-inch cold-hammer-forged steel barrel is chrome-lined for long service life and easy maintenance. It remains unthreaded for compliance in restrictive jurisdictions while still delivering excellent accuracy with standard .45 ACP loads.
A full-length Picatinny rail runs the top of the receiver, giving you instant mounting space for optics or red dots. A retractable underside accessory rail deploys when needed for lights or lasers, then tucks away to keep the profile sleek.
The technopolymer frame, stock, and handguard keep weight down and resist corrosion. The thumbhole stock integrates a comfortable pistol grip, and the 14-inch length of pull suits a wide range of shooters.
True ambidextrous operation is built in: the magazine release, charging handle, safety, and even ejection direction can all be reversed without special tools. Field-stripping into four major assemblies is likewise tool-less, making cleaning straightforward.
Because the carbine shares single-stack magazines with Beretta Cougar and Px4 pistols in .45 ACP, owners of those handguns gain seamless magazine interchangeability—an efficient solution for training and logistics.
