Design and Mechanical Highlights

The GRAND POWER SP45A3 is built around a delayed roller blowback system in a UMP-style pistol package chambered for .45 ACP. That delayed-roller action smooths recoil impulse and improves follow-up shot recovery compared with straight blowback in large-bore pistol-caliber platforms. The included SB Tactical Brace turns the pistol chassis into a stabilized defensive rig without adding unnecessary length.

Controls and Ergonomics

An ambidextrous magazine release allows operators to use either a button or a paddle style release depending on preference and mission requirements. The extended 2-piece USGI milspec AR15 trigger receiver promotes a familiar, consistent trigger interface for shooters already trained on AR-pattern controls.

Magazine Capacity and Reload Speed

This package ships with three 20-round UMP-style .45 ACP magazines, providing higher sustained capacity for defensive use while keeping the overall profile compact for vehicle or CQB environments.

Suppression-Ready and Sighted for Practical Use

The SP45A3 features a .578×28″ threaded barrel suitable for mounting suppressors or compensators and comes with built-in front and rear sights for immediate iron-sight acquisition. A hard plastic case is included for transport and storage.
