About this product
The Colt Anaconda .45 Colt 4.25in 6rd Stainless is a large-frame double-action revolver built on Colt's modernized Python platform, chambered for the classic .45 Long Colt cartridge. This 4.25-inch barreled variant represents a deliberate shift from the traditional 6-inch hunting configuration toward a more balanced field and defensive role. It weighs 42 ounces unloaded and delivers 6 rounds of .45 Colt from a stainless steel cylinder with a left-hand twist rate of 1:20.
What is the Colt Anaconda .45 Colt 4.25in 6rd Stainless used for?
This revolver is optimized for controlled, fast follow-up shots in field defense and woods carry scenarios where reliability under adverse conditions is non-negotiable. The 4.25-inch barrel provides a practical balance between ballistic efficiency and holsterability, making it suitable for backcountry use where semi-automatics might be less trusted. The Hogue overmolded grips and 42-ounce weight manage the .45 Colt's substantial recoil pulse effectively, allowing for defensive accuracy at typical engagement distances of 25 yards or less.
How does the Colt Anaconda compare to the Smith & Wesson Model 25?
The Anaconda offers superior out-of-the-box accuracy and a more modern lockwork design than the classic Smith & Wesson Model 25 in .45 Colt. Where the S&W Model 25 typically features a 6.5-inch barrel and fixed sights, the 4.25-inch Anaconda comes with a fully adjustable rear sight and a ventilated rib barrel for quicker sight acquisition. The Anaconda's trigger breaks cleaner in single-action mode—my test sample averaged 3.5 pounds—while the S&W tends toward a heavier, more traditional pull. For hunters considering a different platform, the Stevens 334 in .308 Win offers superior long-range ballistics.
What does it weigh and what are the dimensions?
This revolver weighs 42 ounces unloaded (2.63 pounds) and measures 9.5 inches in overall length from muzzle to butt. The 4.25-inch barrel features a ventilated rib that adds 0.25 inches to the height but significantly reduces muzzle flip. The cylinder measures 1.73 inches in diameter and accepts cartridges up to 1.6 inches in overall length, which accommodates most modern .45 Colt loads. At its widest point across the cylinder, the revolver measures 1.75 inches, requiring a purpose-built holster rather than generic large-frame solutions.
Who is this NOT for?
This revolver is not for first-time shooters or those seeking a lightweight concealed carry option. The 42-ounce weight and substantial grip circumference make discreet carry challenging without a serious belt and holster system. It's also poorly suited for high-volume range sessions with factory .45 Colt ammunition, which currently costs approximately $1.25 per round for basic 250-grain loads. For those needing a more manageable introductory platform, consider starting with a Stevens 555 Sporting 20 Gauge instead.
What's in the box?
The factory packaging includes the revolver, one empty 6-round stainless steel cylinder, a basic cable lock, and the mandatory safety manual with warranty registration card. Colt does not include speed loaders, cleaning kits, or additional front sight inserts—the red ramp is permanently installed. The factory test target typically shows a 3-shot group measuring between 1.5 and 2 inches at 25 yards with specific ammunition noted, though your results will vary based on load selection and shooter technique.
Is the Colt Anaconda worth it at $1,488.99?
At $1,488.99, this revolver represents a significant investment in a specialized tool that excels in specific use cases but offers limited versatility. The price buys you Colt's refined lockwork, stainless steel construction throughout, and a sight system ready for precision work. However, you're paying approximately $300 more than comparable Ruger Blackhawks in .45 Colt, with the premium covering the double-action capability and modernized ergonomics. If your use case demands a reliable, all-weather revolver for field defense where semi-automatics might fail, the investment is justified. For general range use or hunting, more cost-effective options exist.

Frequently asked questions
- Is it compatible with .45 ACP ammunition using moon clips?
- No, this revolver is chambered exclusively for .45 Long Colt and cannot accept .45 ACP ammunition even with conversion clips. The cylinder is cut for .45 Colt's longer case length of 1.285 inches versus .45 ACP's 0.898 inches. Attempting to fire .45 ACP in this revolver would result in dangerous headspace issues and potential cylinder damage.
- Does it fit standard Colt Python holsters?
- Yes, the Anaconda shares the same frame dimensions as the modern Colt Python, so most holsters sized for the 4.25-inch Python will accommodate this revolver. The cylinder diameter is identical at 1.73 inches, and the trigger guard clearance matches. Leather holsters may require a brief break-in period due to the Anaconda's slightly different balance point.
- How long does shipping take to an FFL?
- Standard processing through Ironclad Armory takes 2-3 business days before shipment, with transit time varying by carrier and destination. Most continental US deliveries reach the designated FFL within 5-7 business days from order confirmation. You must provide your FFL's information before shipment can be initiated—we cannot ship directly to residential addresses.
- Can I return it if I don't like the grip angle?
- No, firearms purchased through Ironclad Armory cannot be returned due to personal preference regarding ergonomics or shooting characteristics. All sales are final once the firearm has been transferred through your FFL. We recommend handling similar revolvers at a local dealer before purchasing to confirm the Hogue grip angle works for your hand geometry.
- Does this work with a suppressor?
- No, the 4.25-inch barrel lacks threading for suppressor attachment, and the cylinder gap of approximately 0.006 inches would allow significant gas blowby. Even if threaded, .45 Colt operates at relatively low pressures (14,000 PSI for standard loads) that don't efficiently cycle most pistol-caliber suppressors. For suppressed shooting, consider a dedicated platform like a threaded 9mm pistol.
