There are a number of good videos out theater on disassembly and reassembly of the Colt C & B revolvers - the '51 & '61 Navies, '60 Army, Dragoons, etc. are all of the same operational design. Watch the videos and re-watch them until you understand how the revolver works and the function of each part - it isn't a great mystery that only some people can understand.
When you put the trigger back in and then reinstall the two leg spring that is the last part to be put in before reinstalling the trigger guard, 1. make sure that the spring is installed correctly so that the long leg fits in the slot and presses on the trigger, (the short leg applies pressure on the bolt) and, MOST IMPORTANTLY, make sure the trigger is puller all the way FORWARD (towards the muzzle end) and that the trigger spring leg applies downward on the trigger, When reinstalling the spring and the spring screw into the frame, it is not necessary to "reef" on the screw. On my Colt clones, I usually gently tighten the screw and then back it off about an 1/8 turn. They aren't going to go anywhere because the spring and screw is "captured in the milled spring channel in the bottom of the frame and the trigger guard.
Don't fret - you haven't done anything that can't be fixed and you aren't the first person to have this happen. Once you have disassembled and reassembled your Colt clone a few times and understand the function of each part, it will become old hat. Good luck!
NOTE: When I posted this, I had about a half a dozen things on my mind and mis-stated that the short leg of the spring applied pressure to the trigger as the trigger spring - sorry - it is indeed the long leg that applies pressure for the trigger as stated in the post after this one. Make sure that the installed and then pulpit towards the muzzle, as you install the spring fit it in the notch and then tighten the spring screw. My apologies.
