Beretta D Hammer Spring for PX4 / 92 / 8000 Series Pistols - Steel

The Beretta D Hammer Spring (EU00043) is a factory steel replacement hammer spring designed to lighten the double-action trigger pull on Beretta pistols. Commonly referred to simply as the "D spring," this replacement noticeably reduces first-shot DA effort without sacrificing ignition reliability, making it one of the most popular trigger upgrades for PX4, 92, and 8000 series owners.

This OEM spring is rated for use across the Beretta PX4 Series, 92 Series, and 8000 Series pistols. Beretta specifically recommends pairing the D spring with their Competition Fire Control and Competition Steel Trigger components on PX4 builds for a match-grade feel.

This is a genuine Beretta factory part, sold individually in an unfinished steel finish.
