TriggerTech AR-9 Competitive Single Stage Trigger – 3.5 lb Flat

The TriggerTech AR-9 Competitive single-stage trigger (brand part no. AR9-SBB-33-NNF) is a drop-in upgrade purpose-built for AR-format 9mm carbines, breaking at a crisp 3.5 lbs with a flat trigger shoe. It delivers the same true zero-creep, sub-0.030 inch tactical reset that made TriggerTech’s AR15 line popular, adapted for the shorter-stroke pistol caliber platform. Competition shooters running 9mm carbines in USPSA, 3-Gun, or PCC divisions rely on this kind of consistency to keep splits fast without sacrificing control. Hardened 440C stainless internals mean the trigger keeps its factory-crisp feel long after a basic mil-spec trigger would start to wear.

Frequently Asked Questions

Is this trigger rated for pull weight consistency over time? Yes, because it doesn’t rely on coating or lubrication of the engagement surfaces, pulls stay consistent even after thousands of rounds.

Can I install this myself? TriggerTech recommends a gunsmith perform the install since it requires fully detail stripping the lower receiver.

Does this fit a standard 5.56 AR-15? No, this version is built specifically for AR-format 9mm carbines.
