Maybe , just maybe the little foot of the loading gate spring has poped out of place. That will wonkey the loading gate all up. With the cyl. out you should be able to push it back in with a screwdriver or somesuch.
Also, you can leave the cyl. out while troubleshooting but put the pin back in all the way. That will keep the transfer bar from sticking under the firing pin preventing it from being cocked.
Is the gun filthy dirty? Been sitting a long time?
Can you push the button and remove the cylinder pin?
You try spraying a lubricant on the loading gate?
Old Model or New Model?

What have you tried?
I wonder if loading gate dry or in a bind, etc.
Is gun UNloaded?
Telling us what you're already tried will limit questions needing asked any maybe narrow things down a bit,
Jpsnides,jpsnides,
On a New Model Blackhawk/ Super Blackhawk, you do NOT cock/touch the hammer to open the loading gate. You simply open the loading gate. That is part of the re-design that makes it a New Model.
