Description
This Sig Sauer flat skeletonized trigger is a direct replacement for your stock P320 trigger and brings a meaningful upgrade to how your pistol feels in hand. The flat design positions your finger lower on the trigger face, which increases your mechanical leverage and promotes a smoother, more consistent break. You're looking at roughly a 30% reduction in trigger pull weight compared to what shipped with your P320.
The Flat Design Advantage
The flat trigger profile changes the entire ergonomic equation. Instead of a curved face that can place your finger at different heights depending on your grip, you get a consistent engagement point that lets you build a repeatable shot process. This matters whether you're running drills at the range or working on precision at distance.
Skeletonized Profile for Reduced Weight
The skeletonized profile cuts mass without sacrificing structural integrity. That lighter trigger also means less inertia to overcome, which translates to a faster reset and snappier feedback. Built from stainless steel with a black finish, it's designed to hold up through years of use without corrosion or wear.
Installation and Compatibility
This trigger is compatible with P320 platforms across the board, including the X-Five, Compact, Subcompact, and X-Compact variants. Keep in mind that installation requires taking your pistol beyond a basic field strip, so many people opt to have a certified gunsmith handle it. The factory recommends using qualified armorers for installation to ensure everything functions properly.

Frequently Asked Questions
Will this flat trigger fit my P320 X-Compact or other variant models?
Yes, this trigger is compatible with all P320 platforms including the X-Five, X-Compact, Compact, Subcompact, M17, and M18 models. It's a direct replacement for the stock trigger on any of these variants. Just verify your model before ordering to be certain.
How much lighter is the pull compared to the stock trigger?
The manufacturer reports an approximately 30% reduction in trigger pull weight. The actual feel improvement varies based on your individual setup, but owners commonly report a noticeably crisper and cleaner break with this trigger compared to factory specs.
Can I install this trigger myself, or do I need a gunsmith?
Installation requires disassembly beyond a basic field strip. While it's not impossible for someone with mechanical experience, Sig Sauer recommends having a certified armorer handle the installation to ensure everything functions safely. Improper installation can affect reliability, so professional installation is the safest route.
What's the difference between this skeletonized version and other P320 flat triggers?
The skeletonized profile cuts the trigger weight without removing material from critical structural areas. This results in a faster reset and lighter feel compared to solid triggers, while the flat face gives you that improved leverage and consistency. It's a factory option from Sig Sauer, so you know it's engineered for your P320.
