Atlas Custom Works CNC Aluminum Trigger for SIG Air / VFC P320 M17, M18, X-Series GBB Pistols, Gold

Factory triggers on SIG and VFC P320 GBB pistols are functional but often heavy and gritty. The Atlas Custom Works CNC aluminum trigger replaces that with a lighter, smoother pull. It's a direct drop-in for the M17, M18, and X-Series—no gunsmithing required.

What changes. The aluminum construction replaces the polymer factory part, and the machined surface gives a cleaner break. You'll notice the difference in semi-auto follow-up shots, where trigger reset and pull weight matter most. It won't fix a worn sear or solve gas pressure issues, but it does remove one variable from the equation.

Fit and finish. CNC-machined from aluminum in gold. The finish resists wear and corrosion, and the color stands out against most black or FDE frames if that's part of your build aesthetic. It's a single component—just the trigger. Installation is straightforward if you're comfortable field-stripping your pistol and swapping small parts.

Compatibility. SIG Air and VFC P320 series GBB only: M17, M18, and X-Series models. This does not fit other platforms or non-GBB P320 replicas. Check your pistol model before ordering.
