The Beretta JM4PX915 magazine delivers reliable feeding and consistent performance for PX4 Storm pistols. This factory-manufactured magazine ensures optimal compatibility and maintains the precision standards Beretta pistols are known for.
What Makes This Different
The steel construction provides superior durability compared to polymer alternatives, withstanding repeated loading cycles and drops without cracking. Beretta's proprietary spring design maintains consistent tension across all 15 rounds, reducing feeding malfunctions that can occur with aftermarket magazines. The anti-tilt follower design prevents nose-diving and ensures smooth chambering of the final rounds.
