Description
There is a reason the 4-inch .357 Magnum revolver hung on duty belts for decades. It is the size that does a little of everything well, and the Rossi RM64 brings that classic formula back at a price that makes sense. You get a medium steel frame, a six-shot cylinder, and a double action/single action trigger that has been earning real praise for how clean it breaks, especially the single action pull. The matte black finish gives it a no-nonsense look and shrugs off wear and moisture better than an old-school blued gun.
Why the RM64 Earns Its Keep
The 4-inch barrel wears a full-length underlug, which adds weight right where you want it. Combined with the steel frame and textured rubber grips, that heft soaks up magnum recoil noticeably better than smaller snub guns, so a full cylinder of .357 does not leave your hand stinging. When you want cheap, relaxed practice, load up .38 Special and shoot all afternoon. Up top, a serrated ramp front sight pairs with an adjustable rear, so you can dial in your point of impact for whatever load you settle on, from light target wadcutters to full-house hunting rounds.
Rossi RM64 Details Worth Noticing
The cylinder release pushes forward in the familiar spot and the cylinder is profiled to work with speed loaders, so reloads stay quick. The hammer has a wide spur for easy single action cocking, the trigger face is smooth and wide, and an internal hammer block adds a layer of drop safety without any keyed lock on the frame. Fit and finish on these has impressed a lot of folks who did not expect this much polish at this price point.
Where the RM64 Fits
This is the revolver for the person who wants one gun to cover home defense, range time, trail carry, and woods duty. Load snake shot for the trail, magnums for the nightstand, and .38s for practice. It rides comfortably in a belt holster all day and pairs naturally with a .357 lever gun if you like keeping calibers simple.

Frequently Asked Questions
Can the Rossi RM64 shoot .38 Special ammo?
Yes. Like any .357 Magnum revolver, the RM64 safely fires both .357 Magnum and .38 Special, including +P loads. Most owners practice with cheaper, softer-shooting .38s and keep magnums loaded for defense or field use. Just never try it the other way around, as .357 will not chamber in a .38-only gun for good reason.
How does the RM64 handle .357 Magnum recoil?
Better than you might expect. The steel medium frame, full-length underlug barrel, and rubber grips add weight and cushion right where it counts, so full-power magnums stay controllable. It is a big step up in comfort from shooting magnums through a lightweight snub gun.
Does the Rossi RM64 have adjustable sights?
Yes, this 4-inch model pairs a serrated ramp front sight with an adjustable rear sight, the same setup found on the longer-barreled RM66. That lets you fine-tune your point of impact across the wide spread of .38 Special and .357 Magnum bullet weights and velocities.
Is the RM64 a good choice for carry or is it strictly a range gun?
It genuinely does both. The 4-inch barrel and medium frame keep it compact enough for belt carry, and reviewers regularly point to it as an all-day outdoors and trail companion. At the same time, the sight radius, adjustable sights, and solid DA/SA trigger make it plenty accurate for range work and even close-range handgun hunting.
