"Out of the box, this is maybe 2/5 stars because it is too hot to use at airsoft fields, because its power is inconsistent (450-550fps in double action, and 550-650fps when fired in single action), and because it Has. No. Hopup.
In terms of this model's potential for (advanced) after-market modification, this gets 4/5 stars. It would be 5/5 if you could buy upgrade parts yourself! This has the standard Dan Wesson revolver layout (in my favorite finish), and so there are lots of clever things you can do to it. Firstly, you can cut down the trigger spring to make it field-legal. The power fluctuation is more difficult to solve; i had to not only lube the trigger mechanism with silicon, but mill my own, longer barrel-nozzle attachment (and by mill, I mean clamp a metal file to a table, stick the revolver barrel in a screw gun, sand an AUG hopup down to just a barrel-shaped-tube, attach it to said barrel and then use the screwgun/file to "mill" it down to just-the-right-shape to fit in the revolver cylinders and feed a bb to the barrel). I also had to adjust the barrel spring to get a stronger, deeper positive engagement between the barrel-nozzle (the bb feed tube attached to the back of the barrel) and each revolver cylinder (where the shells/bbs are loaded). This also pushes the back of each shell into the co2 nozzle behind it, sealing the whole path from gas tank to muzzle break. That got me down to maybe a variance of 350-380fps, which is acceptable. This mod is a pain but worth it if you want a precise weapon.
You can also build a hopup without too much trouble, for which there are plenty of guides out there. On top of that, you can 3D-print shells for this that carry up to 7 bbs, which I have not done yet but plan to try, with the power cranked all the way up!!! You can add washers to the spring, or even drive a correctly-sized machine screw through the two thin layers of soft aluminum below the spring base-box, thus pushing the base-box / spring above it upwards, granting you infinitely adjustable FPS! The trigger itself was too difficult for me to modify, so you can probably expect your single action shots to always be more powerful by ~100fps.
Finally, the gun body is very sturdy, so you can count on it in the field, and I also took the liberty of hitting it with heavy metal objects and rubbing it with metal files, to give it a nice marred, "battle-scarred" look.
