Failure Resistant Extractor for Sig Sauer P320

This is a direct replacement extractor for the Sig Sauer P320, manufactured from 17-4PH stainless steel. It solves the intermittent extraction and erratic ejection patterns that can occur with factory extractors, particularly on high-round-count slides or pistols used in competition and training. The redesigned extractor hook geometry provides a more positive grip on the case rim, while the thicker claw section reduces the risk of breakage under sustained use.

Compatibility

• Sig Sauer P320 (all full-size, carry, compact, subcompact, and X-Series variants)
• Factory Sig Sauer slides and barrels only
• NOT compatible with aftermarket slides or barrels (including custom-machined, billet, or 80% builds)

Key Features

• Machined from 17-4PH stainless steel – higher tensile strength than factory MIM extractors
• Optimized hook geometry for consistent rim engagement and uniform ejection angle
• Drop-in replacement for factory P320 extractor – no slide modifications required
• Fits both standard and suppressor-height sight slides

Install Difficulty: 2/5

Requires: 1/16″ punch, small hammer, needle-nose pliers. Remove slide, depress extractor plunger, drift out retaining pin, slide extractor rearward. Reverse to install. No fitting or filing needed. Expect 5–10 minutes for first-time swap.

FAQ

Will this work with my P320-M17 / M18?

Yes. The extractor is compatible with all factory P320 slides including the military-contract M17 and M18 variants. Verify your slide is factory Sig – not aftermarket.

Does this require any modification to the slide or firing pin safety?

No. It is a direct factory-replacement part. Use the same extractor plunger and spring from your original assembly.

Why does this not work with aftermarket slides?

Aftermarket slides vary in extractor channel dimensions, breech face geometry, and ejector location. This extractor was engineered specifically to factory Sig P320 tolerances. Installation in non-factory slides may cause extraction failure or damage.
