The CT3D Trigger Tuning System gives you full control over your ACE handset's trigger feel with a modular kit of swappable components. The kit includes four precision-machined sear profiles, three color-coded spring weight levels, spring caps for fine-tuning, and a hard trigger stop. Mix and match to dial in exactly the pull weight, wall feel, and reset you want. Sear Profiles Sear 1 (Duty/Firm): Strong, defined wall with a crisp break Sear 2 (Balanced): Moderate wall with a clean break, good all-around feel Sear 3 (Competition/Reduced Wall): Minimal wall, light and fast Sear 4 (Rolling): Smooth, progressive pull with no distinct wall Spring Weights Red (Heavy): Maximum resistance, closest to a stock striker-fired feel Yellow (Medium): Middle ground, great for balanced setups White (Light): Lightest pull, ideal for competition-style configs Spring Caps Snap a cap onto any spring to add extra tension. Great for fine-tuning between weight levels. Hard Trigger Stop Eliminates overtravel for a shorter, snappier reset. Drop it in for a crisper shooting experience. Popular Setup OEM Sear + Red Sear Spring + Yellow Reset Spring with Cap. This gives you a hard defined wall at roughly 4.5 lb, similar to a striker fire factory feel.
