Trigger Pull: The trigger on the Umarex Marlin Old West CO2 BB Revolver is single-action-only, so you must cock the hammer before each shot. That removes most of the trigger travel and effort, giving the Marshal a short, light, and easy-to-manage pull. It’s ideal for deliberate, accurate shooting, but less suited to action-style rapid fire unless you’ve got a very fast thumb.
Accuracy: We haven’t tested the Marlin Old West model specifically, but it should perform very similarly to the John Wayne Marshal CO2 BB revolver, they’re nearly identical aside from licensing, safety, and magazine placement. In our field test of the John Wayne Marshal it averaged closer to 360 fps rather than the claimed 420 fps and produced roughly a 4-inch, 10-shot group at 30 feet. You can watch that video here; we will hope to be posting a dedicated field test for the Umarex Marlin Old West soon.
Build Quality: There’s not a lot to get excited about in terms of materials, the Umarex Marlin Old West CO2 BB Revolver is mostly plastic with some internal metal parts like the barrel, trigger, hammer, and CO2 components. It follows the common two-half, screwed-together budget construction, which looks cleaner on the side where the screws are hidden. At just over a pound it’s fairly light. With relatively few moving parts, it should be reasonably reliable; the mechanical components do what they need to do and feel suitably solid for the price.
Realism: At first glance the John Wayne Marshal CO2 BB revolver resembles a Colt Single Action Army Revolver in shape and size, but it’s much lighter, about half the weight. The lack of real bullet openings in the cylinder (when viewed from the front) reduces realism. We used to the newer generation of revolvers with working cylinders and loadable, removable shells; those are pricier and hold fewer rounds, but they offer a much more authentic experience.

Cons:
Comments: The Umarex Marlin Old West CO2 BB Revolver is a solid choice if you want an old-west single-action cowboy BB shooter for less than the nearly identical John Wayne Marshal (it’s about $50 cheaper). If you want more authenticity, consider one of the shell-loading Single Action Army style revolvers, they cost more, shoot a bit slower, and carry fewer rounds, but they deliver a much higher level of realism.
