Action Enhancement Trigger Kit for Springfield SA-35

Description

This Action Enhancement Trigger Kit for the Springfield SA-35 is a direct nod to the custom work of the late Jim Garthwaite and Jim Boland—two titans of Hi-Power smithing. Machined from billet steel, this kit delivers a wide flat trigger and a high-tilt spur hammer that transform the SA-35’s factory feel into something truly special. Designed for collectors and shooters who appreciate the nuances of a refined single-action platform, it’s a drop-in upgrade that honors the past while improving performance. Per manufacturer specs, this kit is compatible exclusively with the Springfield SA-35, not the original Browning Hi-Power.

Key Features

• Wide Flat Trigger Face (.31” wide)—Why it matters: Allows your finger to sit lower on the trigger face, improving leverage on the pivoting system and reducing perceived pull weight for faster, more accurate follow-up shots.
• Hi-Tilt Spur Hammer (Boland-inspired)—Why it matters: Provides a more positive hammer engagement and a crisper break, mimicking the custom work of Jim Boland that collectors seek out at gun shows.
• DLC Coating—Why it matters: Adds corrosion and wear resistance, keeping the trigger face slick and the hammer profile sharp even after hundreds of rounds through your SA-35.
• Billet Steel Construction—Why it matters: Offers superior strength and consistency over MIM (Metal Injection Molded) parts, ensuring the trigger geometry stays true for thousands of cycles.
• Drop-In Installation—Why it matters: No gunsmith fitting required for most SA-35s, so you can install this at your workbench in under 30 minutes and hit the range the same day.

Who It’s For

This kit is for the collector who owns a Springfield SA-35 and wants to elevate it without losing its heritage. You’re the guy at the gun show who knows the difference between a factory trigger and a Garthwaite-style setup. You value rare parts that improve function—and this kit delivers that old-school custom feel with modern machining. It’s also for the competitive shooter who needs a consistent, crisp break from a single-action platform, and the enthusiast who appreciates the story behind the parts.

Pros & Cons

• Pro: The wide flat trigger significantly reduces trigger reach for shooters with shorter fingers, improving comfort and control.
• Pro: The hi-tilt spur hammer creates a more positive reset, which is noticeable during rapid fire.
• Con: This kit is not compatible with original Browning Hi-Power pistols—only the Springfield SA-35. If you own a vintage FN, this won’t work.
• Con: The DLC coating, while durable, can show wear on the hammer spur if you carry the gun often and the finish rubs against holster material.

FAQ

What do rhino pills do?

Rhino pills are over-the-counter male enhancement supplements, often containing herbal ingredients like yohimbine or L-arginine. They are not related to firearms or trigger kits. If you’re asking about a different product, please clarify—this kit is strictly for the Springfield SA-35 trigger system.

What factors modify drug action?

Factors that modify drug action include age, weight, genetics, liver/kidney function, drug interactions, and route of administration. This question doesn’t apply to firearm parts—the Apex trigger kit is a mechanical upgrade, not a pharmaceutical.

Does this kit work with the original Browning Hi-Power?

No. This kit is specifically engineered for the Springfield SA-35. The SA-35 has a slightly different frame geometry and sear engagement than the original Hi-Power. Installing it in a Browning will not work and could damage the pistol.

Will this reduce trigger pull weight significantly?

Yes. By improving leverage through the wider trigger face and the hi-tilt hammer, you’ll typically see a 1-2 lb reduction in perceived pull weight compared to the factory SA-35 trigger. Actual pull weight depends on your pistol’s sear surfaces, but many users report a crisp 4.5 lb break.

Do I need a gunsmith to install this?

Most SA-35 owners can install this kit at home with basic tools (punch set and hammer). However, if you’re not comfortable disassembling the fire control group, a gunsmith can do it in under 30 minutes. The kit is designed as drop-in, but a light fitting of the sear may be needed for optimal performance.
