Collecting and selecting a defensive revolver that doubles as a historical piece requires attention to provenance, build details, and practical performance. A rare variant that balances shootability with collector value can serve both roles — as a working firearm and an investment-grade example for display or rotation at the range.

COLT SINGLE ACTION ARMY is a very rare Single Action Army with a 7.5″ barrel chambered in .38 Special. This 2nd Generation SAA, serial number 4182SA, retains actual natural bone grips with “4182” etched into them and “Bill Aaron 1956″ etched into the frame under the grips. Many of the original 7.5″ .38 Special examples were cut down to 4.75″ or 5”, making intact long-barrel examples like this particularly uncommon. Shop this product

Design and historical details

The Colt legacy in single-action revolvers is foundational to American handgun design. This example’s 7.5″ barrel offers a longer sight radius and higher muzzle velocity compared to shorter cuts, which improves accuracy for deliberate shots. The bone grips and the Bill Aaron engraving add documented provenance that serious collectors and tactically minded shooters will value. At $2,799.99 as a Certified Used firearm, it represents a specific market intersection: rare original configuration with verified condition standards.

Practical defensive considerations

The .38 Special is known for manageable recoil, reliable feeding in single-action platforms, and broad ammunition availability. In a defensive context, the 7.5″ barrel is heavier and longer than modern concealed-carry options, making this revolver better suited for home defense, range use, or as a truck/locker firearm where size is less of a limitation. Its balance and sighting make accurate, controlled shots easier for most shooters.

Certified Used status is important: firearms sold with this designation are held to a high standard and include a ‘no questions asked’ return policy, giving buyers confidence in condition and performance. View product details and pricing

Final notes for buyers

If you prioritize originality and documented detail — 4182 etched into the grips, Bill Aaron 1956 under the grips, and the intact 7.5″ barrel on a 2nd Generation SAA — this Colt stands out. For collectors and shooters who want a functional, historically significant revolver, the price point and Certified Used backing make it a compelling option. Check current availability
