The Beretta OEM 17‑round magazine is a great choice—steel-body, reliable feed, and local availability. Just ease in the spring, keep it lightly oiled, and address empty‑slide lock issues if they appear. For ease of loading, a Maglula loader is highly recommended.

• Holds 17 rounds of 9×19 NATO in a steel double-stack design. Fits all APX models (full-size, Centurion, A1, etc.)—flush in full-size, and with a spacer adapter in the Centurion/compact models.

• Initial Use: Load and unload the mag 5+ times to soften the spring .

• Lubrication: Lightly oil follower and inside wall can alleviate feeding resistance.

• Slide Lock Fix: Slightly bend the internal slide-stop spring upward or replace weaker mag springs to restore reliable slide closure.
