The Sig Sauer P320 Forced Reset Device is a drop-in forced reset device designed specifically for the Sig Sauer P320. It replaces the factory disconnector inside the fire control unit and uses the slide’s rearward movement to mechanically force the trigger forward into the reset position.

It allows faster follow-up shots while remaining semi-automatic — one function of the trigger per round.

What Is the P320 Forced Reset Device?

It is a disconnector replacement for the Sig P320 modular pistol. Because the P320 uses a removable fire control unit, the install is performed inside that unit rather than requiring a full trigger group swap.

How It Works

1. You pull the trigger → one round fires.
2. The slide cycles rearward.
3. The modified disconnector uses slide movement to force the trigger forward into the reset position.
4. You pull the trigger again for the next shot.

The system does not convert the P320 into a machine gun. Each round still requires a separate trigger function.

Compatibility

• Designed for the Sig Sauer P320.
• Works with the modular fire control unit design.
• No AR-style buffer or BCG requirements.

Installation Overview

1. Clear the firearm and remove the magazine.
2. Remove the slide and barrel assembly.
3. Access the fire control unit and remove the factory disconnector.
4. Install the Forced Reset Device disconnector.
5. Reassemble the fire control unit and slide.
6. Function check carefully, then live fire.

Install time is typically 10–20 minutes for someone familiar with P320 disassembly.

Final Thoughts
