Whether you’re maintaining a working cowboy gun, restoring a collectible 3rd Gen SAA, or tuning a competition revolver, this blued ejector spring helps ensure your cases clear the cylinder with the smooth, positive feel you expect from a real Colt.

Genuine Colt Ejector Spring for Single Action Army Revolvers
This is not a generic spring or off-brand replacement. Multiple parts houses list Colt part number 50973 as an original Colt Manufacturing ejector spring for the Single Action Army, sold as an OEM Colt component.
Key OEM advantages:
Factory dimensions and spring rate for correct tension on the ejector rod
Designed to work with Colt SAA ejector rod, tube, and frame cuts
Helps preserve the authentic feel and function of a true Colt Single Action Army
If you’re keeping your revolver “all Colt,” this is the right way to replace a tired, bent, or broken ejector spring.
Built for Colt SAA 45LC 5.5" – Compatible with 3rd Gen & More
Brownells and other major distributors list this as the “SAA 45LC 5.5 Blued Ejector Spring” for the Colt Single Action Army, chambered in .45 Long Colt.
Intended for Colt SAA .45 Colt 5.5" (Artillery-length) revolvers
Marked to fit Single Action Army, 3rd Gen, with many sellers noting fitment for later SAA models
Additional parts suppliers reference the same spring as fitting “all models” of the Colt Single Action Army, making it a versatile choice for multi-gun collections
As with any vintage revolver, final fit should always be checked by a knowledgeable gunsmith, especially on early generations or heavily modified guns.
Blued Steel Construction – Durable, Period-Correct Appearance
This blued steel ejector spring is built to stand up to years of cocking, firing, and case ejection while maintaining the classic look appropriate to a Colt SAA.
Benefits of the blued construction:
Corrosion-resistant finish that resists surface rust when properly oiled
Traditional dark blue/black color that visually matches vintage and modern SAA parts
Strong, resilient steel that maintains tension over thousands of cycles
Whether you’re shooting cowboy action, carrying on the ranch, or displaying a collectible in the safe, the blued finish keeps the gun looking “right” while doing its job.
Restore Positive, Reliable Ejection
A weak or damaged ejector spring can make even the finest Colt feel sluggish:
Spent cases don’t clear cleanly
The ejector rod feels mushy or inconsistent
Emptying the cylinder becomes slow and frustrating
Replacing that worn spring with a fresh Colt 50973 ejector spring helps restore:
Positive, authoritative ejection of spent .45 Colt cases
The crisp feel of the ejector rod returning to position
Confidence that your SAA will run as intended in the field, on the range, or in competition
Factory replacement parts like this one are manufactured with the same specs and materials as the original parts, preserving the legendary reliability of Colt’s Single Action Army.
Ideal for Maintenance, Restoration & Cowboy Action Shooting
The Colt SAA 45LC 5.5 Blued Ejector Spring 50973 is an essential small part for:
Routine maintenance on hard-used working revolvers
Restoration projects bringing older 3rd Gen or modern SAA revolvers back to original operating condition
Cowboy action and competition guns, where fast, clean ejection speeds up reloads
Spare parts kits for Colt owners and gunsmiths who routinely service Single Action Army revolvers
At this price point, it’s smart to keep at least one or two of these springs in your parts drawer—especially if you run multiple SAA revolvers or rely on one as a working sidearm.
