The SIG SAUER P320 skeletonized factory flat trigger is a direct replacement for your stock trigger. A 30% trigger pull weight reduction compared to the stock P320 trigger. The flat trigger design gives shooters a lower position on the trigger, which will increase leverage for a smoother, more consistent pull. Installation of these parts kits requires disassembly of your firearm beyond a "field-stripped" condition. Improper installation may result in malfunction, serious injury, or death. SIG SAUER requires that only certified SIG SAUER armorers install these parts kits. Any damage caused by the incorrect installation of these parts kits is not covered by your firearm's warranty, and SIG SAUER will charge for any needed repairs to a firearm damaged by improper use or installation of these parts kits.
