Action Enhancement Trigger Kit for Springfield SA-35

If you’re struggling with the heavy, gritty trigger pull that’s common on the Springfield SA-35, this Action Enhancement Trigger Kit is the fix. It’s a complete drop-in set that replaces the factory trigger, hammer, and sear with precision-machined billet steel components. The wide flat trigger lowers your finger placement for better leverage, while the matched hammer and sear geometry gives you a clean, crisp break without needing to stone or hand-fit anything. The result is a trigger that feels more responsive and comfortable, especially if you’re used to shooting tuned 1911s or Hi-Powers.

Will This Fit My Springfield SA-35?

This kit is specifically designed for the Springfield Armory SA-35. It is not compatible with standard Browning Hi-Power pistols or other SA-35 variants.

Key Features

• Billet Steel Construction: Machined from solid steel for durability and consistent lock-up, with a DLC coating for corrosion and wear resistance.
• Wide Flat Trigger (.31″ face): Allows lower finger placement on the trigger, improving leverage and comfort on pivoting trigger systems.
• Hi-Tilt Spur Hammer: Inspired by Jim Boland’s design, this hammer eliminates the need for a clearance pocket often required on beavertail safeties, while preventing hammer bite with an integrated over-cocking limit pad.
• Mk 1 Balanced Sear: Nose geometry matched to the hammer hook profile for a clean, crisp break without stoning or fitting.
• Balanced Sear Lever & Spring: Completes the action package for a smooth, consistent pull.

Install Difficulty: 3 out of 5

This is a moderate install. You’ll need basic gunsmithing tools: a roll pin punch set, a small hammer, and a bench block. The sear lever spring can be tricky to seat without a slave pin, but we include a detailed install video on our site. Expect 30–60 minutes if you’re comfortable with disassembling an SA-35. If you’re not sure, a local gunsmith can handle it in about 30 minutes.
