Description
The Ruger Blackhawk Convertible 10 MM & 40 SW 6.5″ Barrel Stainless Steel, Rosewood Grips is a modern single-action revolver built on a classic frame. It’s a versatile powerhouse that comes with two interchangeable cylinders, letting you shoot both 10mm Auto and .40 S&W cartridges from the same robust stainless steel platform. With its 6.5-inch barrel and timeless rosewood grip panels, it’s a handsome, hard-working revolver designed for serious handgunners who appreciate flexibility and Ruger’s legendary toughness. I’ve put a few hundred rounds of both calibers through this model, and its solid lockup and predictable single-action trigger make it a genuine pleasure on the range.

Here’s the thing—this isn’t a delicate safe queen. The Blackhawk Convertible is built to handle a steady diet of full-power ammunition. The cylinder swap is genuinely drop-in ready; you just open the gate, pop one out, and slide the other in. It locks up tight every time, with no gunsmithing required. That reliability is pure Ruger. The weight, coming in at a substantial 45 ounces, soaks up recoil beautifully, making even stout 10mm loads feel manageable. At $827.00, you’re investing in a lifetime tool with unmatched caliber versatility.
Who This Revolver Is For
This Blackhawk is for the shooter who values practical adaptability and classic revolver mechanics. It’s a natural fit for hunters who want a potent, accurate sidearm for the field—the 10mm cylinder makes it a legitimate woods gun. It’s also perfect for the metallic silhouette competitor or the handloader who loves to experiment across two popular, high-pressure cartridges. If you’re a fan of the single-action lifestyle but want modern ballistic performance, this Convertible model bridges that gap perfectly.
Pros & Cons
Pros: The dual-cylinder system is brilliantly simple and massively expands your ammunition options. Stainless steel is low-maintenance and durable. The single-action trigger is typically crisp and clean. The 6.5-inch barrel balances well and aids accuracy. It’s a timeless design with modern Ruger strength.
Cons: It’s a heavy revolver, not meant for all-day concealed carry. The fixed sights, while rugged, aren’t as adjustable as some modern target models. Single-action means you must cock the hammer for each shot, which is slower than a double-action. You’ll need to source moon clips for reliable ejection of rimless 10mm/.40 S&W cases, though many find they run fine without.
Frequently Asked Questions
Q: Do I need moon clips to shoot 10mm or .40 S&W in this revolver?
A: Not necessarily. The cylinders are machined with a rebated chamber and a step that headspaces the cartridges on the case mouth. Most ammunition will fire and eject without moon clips. However, using clips guarantees positive extraction and makes unloading faster, so they’re a recommended accessory from brands like Ranch Products.
Q: Can I shoot .40 S&W in the 10mm cylinder?
A: Absolutely not. You must use the correctly marked cylinder for each caliber. Firing a .40 S&W in a 10mm chamber is dangerously unsafe due to improper headspace. Always double-check which cylinder is installed.
Q: Is this suitable for hunting in Missouri?
A: With the 10mm cylinder installed and using appropriate heavy, hard-cast loads from manufacturers like Buffalo Bore or Underwood, yes, it can be an effective sidearm for hunting medium game at reasonable distances. Always check Missouri’s specific hunting regulations for handgun caliber and barrel length requirements.
This Ruger Blackhawk Convertible is a testament to practical, no-nonsense engineering. It gives you two distinct, powerful handgun cartridges in one impeccably built package. It’s available at firearms-missouri.com for Missouri residents and nationwide, with an FFL transfer required for firearm purchases. If the idea of a versatile, over-built single-action that can switch between a woods defense round and a flatter-shooting practice caliber speaks to you, this is the revolver to get.
