About this product
What is the Rossi RM64 .357 Magnum 4″ 6-Round Revolver – Black? It's a Brazilian-made, steel-frame double/single-action revolver chambered in .357 Magnum with a 4-inch barrel and hammer block safety. Built on Rossi's proven R-series platform, this revolver delivers reliable performance for field use and range training where simplicity matters more than custom features. At 9.14 inches overall length and 36 ounces unloaded, it balances controllability with .357 Magnum's full power potential.
What is the Rossi RM64 used for?
The RM64 serves as a field revolver for hunters and hikers who need dependable power in adverse conditions. Its 4-inch barrel provides optimal velocity for .357 Magnum rounds while remaining compact enough for hip carry. The steel construction handles full-power loads without excessive wear, making it suitable for daily carry in rural environments where semiautomatics might jam.
How does the Rossi RM64 compare to the Smith & Wesson 686?
The RM64 delivers 90% of the S&W 686's performance at 60% of the cost, making it the better value for shooters who don't require custom sight options. Where the 686 offers smoother trigger pulls and aftermarket support, the RM64 provides identical ballistic performance from its 4-inch barrel and 6-round capacity at $521.99 versus $900+. For budget-conscious shooters needing .357 Magnum reliability, the Rossi wins on price-to-performance ratio.
What does it weigh and what are the dimensions?
Unloaded weight measures 36 ounces (1020 grams) with an overall length of 9.14 inches and cylinder width of 1.56 inches. The 4-inch barrel provides sight radius of 6.3 inches while keeping holster options versatile—comparable to mid-size semiautomatics like the the Stevens 334 Rifle in handling profile though obviously different in operation.
Who is this NOT for?
This revolver isn't for competitors needing rapid reloads or concealed carry specialists seeking minimal print. The 36-ounce weight and 1.56-inch cylinder width create noticeable bulk compared to polymer-frame semiautomatics. Shooters requiring night sights or trigger jobs should look to custom shops—the RM64's sights are fixed and trigger pull averages 12 pounds double-action.
What's in the box?
You receive the revolver, one 6-round moon clip, and owner's manual detailing disassembly procedures. Unlike some competitors, no cleaning kit or spare grips are included—plan to add $30-50 for basic maintenance supplies. The moon clip allows faster reloading than individual rounds but requires practice to master under stress.
Is the Rossi RM64 worth it at $521.99?
At $521.99, the RM64 justifies its cost through all-steel construction and .357 Magnum capability that outperforms similarly priced semiautomatics in reliability. Compared to Turkish imports like the Tisas 1911, you're getting a proven platform with better parts availability and regulatory clarity — our editorial take for modifications. For shooters needing one revolver to handle both trail defense and range training, this represents solid value without custom features.

Frequently asked questions
- Is it compatible with .38 Special ammunition?
- Yes, the RM64 fires both .357 Magnum and .38 Special rounds interchangeably. .38 Special loads produce 40% less recoil while maintaining identical point of impact at 25 yards. Always confirm chamber dimensions with a gauge if using reloads.
- Does it fit standard holsters?
- It fits holsters designed for K-frame revolvers with 4-inch barrels. The 1.56-inch cylinder width requires leather or polymer holsters with adequate clearance—avoid tight-fitting Kydex meant for slimmer profiles. Expect 2-3 weeks break-in for leather rigs.
- How long does shipping take?
- Ironclad Armory processes orders within 3 business days via FedEx 2Day to your local FFL. Total delivery typically runs 5-7 days excluding state-mandated waiting periods. Alaska and Hawaii shipments add 4-6 days transit time.
- Can I return it if it doesn't fit?
- Returns require unopened factory packaging and incur a 15% restocking fee per Ironclad Armory's policy. Firearms must be returned through your local FFL within 14 days of delivery—no exceptions for California or New York residents due to state laws.
- Does this work with Hogue grips?
- It accepts Hogue Monogrip #80000 series for round-butt K-frames. Installation requires removing the factory grip's retaining bolt with a 3/32-inch hex key. Allow 10 minutes for swap and expect improved palm swell versus factory rubber.
