Full description and what we offer
The Sig Armorer focuses exclusively on customizing and upgrading Sig Sauer pistols through precision gunsmithing. Every component they manufacture—triggers, sears, strikers, disconnectors—is designed to improve the factory action.
They offer two performance tiers for P320 pistols:
Both kits include: - Cradle or Legion flat trigger (multiple colors: black, gold, silver) - Hand-polished hardened sear (17-4 stainless, H900 heat treated, Nickel Boron Nitride coated) - Chrome disconnector (17-4 stainless, sub-10µ surface finish) - Optimized trigger bar with hard point takeup stop - Polished and contoured striker - 9–10 custom springs for weight tuning
Kit prices: $275–$345 depending on trigger type and specs.
The ARC (Advanced Recurve Combat) trigger line addresses a core factory design flaw. Stock Sig P-Series triggers have a curved face that allows finger migration and trigger guard drag, increasing perceived movement and flinch.
The Sig Armorer's ARC triggers flatten the face side-to-side while maintaining a gentle top-to-bottom curve for finger support. Features include: - CNC machined from 1018 steel - QPQ wear-resistant coating - Micro texture for control (gloved, muddy, or wet conditions) - Reduced DA takeup and forward SA break point - Fits P220, 224, 225, 226, 227, 228, 229
The ARC-G variant adds a memory bump/blood gutter for quick finger placement and debris management.
Price: $60 (sale price from $65)
Fitting required about 5% of the time due to frame variations—performed at no extra charge.

All custom kits ship with multiple spring options for weight tuning—you're not locked into one trigger pull weight.
