Let’s talk about the Heritage Mfg Rough Rider Big Bore. In my years of handling everything from custom 1911s to duty-grade Glocks, I’ve developed a real appreciation for a simple, honest single-action revolver. There’s a purity to the platform that modern polymer-framed striker-fired guns just can’t match. It’s a mechanical conversation between you, the trigger, and the cylinder. The Rough Rider series has always been the go-to for affordable cowboy action, but the Big Bore variant changes the script. It’s not just a .22 plinker anymore; this is a Heritage built to handle the classic .45 Colt cartridge. That’s a significant step up in both capability and presence. For the DIY enthusiast or the tinkerer who appreciates the internals, this represents a fascinating blend of traditional design and modern, accessible manufacturing.

What You’re Getting with the Rough Rider Big Bore
This isn’t a replica of a specific historical model, but rather a functional homage to the single-action army revolvers of the late 19th century. The frame, cylinder, and 5.5″ barrel are all built to accommodate the .45 Colt cartridge, which means the proportions feel substantial and correct in the hand. The one-piece cocobolo grips aren’t just for show; they provide a solid purchase and that classic look. From a gunsmithing perspective, the inclusion of a frame-mounted inertia firing pin and a transfer bar safety is noteworthy. This is a modern safety feature integrated into a traditional design, preventing an accidental discharge if the hammer is struck without the trigger being pulled. It’s a thoughtful addition that doesn’t interfere with the classic manual of arms.
Key Features & Build Quality
The blue finish on this model is a classic carbon steel bluing. It’s a durable, traditional finish that wears in, not just wears out, developing character with use. The action is straightforward—pull the hammer to full cock, the cylinder rotates and locks, and the trigger breaks. There’s no double-action capability, which keeps the mechanism simple and robust. The sights are a fixed blade front and a notch in the top strap, true to the period. Don’t expect target-grade adjustability; this is for instinctive shooting at practical ranges.
I’ve handled a lot of budget revolvers, and the fit on this Big Bore is a step above what you might expect. The cylinder lock-up is positive, and the timing, right out of the box on the units I’ve inspected, is solid. The transfer bar system is a key point of reliability. It’s a simple stamped part that rises into place only when the trigger is pulled fully to the rear, allowing the hammer to strike the firing pin. This design is proven and easy to understand for anyone who likes to disassemble and maintain their own firearms.
Pros & Cons: An Honest Assessment
- ✅ Authentic Single-Action Experience: The manual of arms is pure Old West, offering a deliberate and satisfying shooting rhythm.
- ✅ Exceptional Value for a Big Bore: Chambering in .45 Colt at this price point is virtually unheard of from a major manufacturer.
- ✅ Modern Safety in a Classic Package: The transfer bar system adds a crucial layer of safety without altering the external profile or function.
- ✅ Great Platform for Tinkering: The simple design is ideal for learning basic revolver smithing, polishing actions, or fitting aftermarket grips.
- ✅ Quality Cocobolo Grips: The one-piece wood grip is well-fitted and far superior to the plastic or laminate often found in this tier.
- ❌ Fixed Sights: They are period-correct but not adjustable. If your point of impact is off, you’re filing the front sight or learning hold-overs.
- ❌ Single-Action Only: This is a feature, not a bug, but it limits practical defensive use. For a modern defensive revolver, see our double-action revolvers.
- ❌ Heavy Trigger Pull: The single-action pull can be on the heavier side and may benefit from a spring kit or careful polishing for a smoother break.
Who This Revolver Is For (And Who Should Look Elsewhere)
Buy it if: You’re a cowboy action shooting enthusiast on a budget, a firearms tinkerer who loves classic mechanics, a recreational shooter wanting a fun, low-cost entry into big-bore revolvers, or a collector looking for a shooter-grade .45 Colt that won’t break the bank.
Skip it if: You need a modern defensive sidearm (consider a striker-fired pistol), demand target-grade adjustable sights, prefer the faster engagement of a double-action revolver, or are looking for a historically exact replica of a specific Colt or Remington model.

Frequently Asked Questions
Is the Heritage Rough Rider Big Bore safe to carry with all six chambers loaded?
Yes, due to the transfer bar safety system. The firing pin is only struck when the transfer bar is lifted into place by a full pull of the trigger. This means the hammer can rest on a loaded chamber without risk of a discharge from an impact on the hammer.
What kind of .45 Colt ammunition can I use in it?
Stick to standard-pressure .45 Colt ammunition. This revolver is not designed for modern high-pressure or “Ruger-only” loads. Always consult the manufacturer’s manual. For recreational shooting, 250-grain lead round nose factory loads are ideal and widely available.
Can I use a .45 ACP cylinder in this Big Bore model?
No. The Heritage Big Bore is specifically chambered for .45 Colt. The cylinder and frame are dimensioned for that cartridge. Convertible cylinders are typically offered on their .22 LR/.22 WMR models, not the large-bore versions.
How difficult is it to disassemble for cleaning?
Field stripping is straightforward for basic cleaning. Removing the grip panel allows access to the backstrap and some internal components. Full disassembly of the lockwork requires specific pins to be driven out and is best attempted by those with revolver smithing experience or with a detailed guide.
Is this suitable for hunting?
With the right standard-pressure .45 Colt loads and within its effective range (typically 50 yards or less for most shooters), it could be used for small to medium game. However, its fixed sights and single-action operation make it less than ideal compared to a modern hunting revolver with adjustable sights.
