due to the fact that real revolver's cylinders are small (and therefore, mccree's gun) they could only fit one or two rival rounds (due to them having such a high width.)

and the length of the hammer draw is so small that there is now way for it to reach a hundred, or at least eighty fps. Yep, Zuna's reasoning is correct. It's not easy to make a Nerf blaster's internals after an already existing shell and expect it to have RIVAL standards. And the draw is really short, and I don't even know where they would put the plunger. Maybe in the grip like other hammer action blasters, but the grip is pretty thin. No way you'd get high RIVAL-standard FPS readings from that.

However, the hammer isn't exactly purely cosmetic. It actually cocks back when you prime the blaster, and springs back when you fire the blaster. You can also manually cock the hammer like a Hammershot, and release it using the trigger (it's rigged to the trigger that way) but of course it doesn't prime the actual blaster. The hammer makes for a nice priming indicator but that's it.
