Is it supposed to be like this? Do I need to adjust the trigger screw? If so, how should I do that? The triggerguard is pinned on and I’d rather not take it off to adjust the screw if I can help it.

As noted above, you can adjust the trigger by turning the screw which is located between them. There were also some excellent suggestions for tools you can use to accomplish this. However... Have you tried just using your fingers? If the triggers are unset, you
might be able to turn that screw with your thumb and forefinger. Turn the screw out a little to make the hair trigger less sensitive. Whether you use your fingers or a tool, you should be able to turn the screw without removing the triggerguard.
You can test the triggers without firing the rifle. Just make sure the hammer is all the way down.
Never trip your set triggers with the hammer at half cock.
I don't want to complicate things too much, but set triggers may be single lever or double lever. Most of the double set triggers that you get nowadays are the double lever type, which means you can fire the gun with the triggers set or unset because both the front and rear triggers have blades to engage the sear arm. You can squeeze the front trigger just like a "normal" trigger without setting it to fire your rifle. The only single lever double set triggers I know of in current production are the #0001 triggers from
R. E. Davis. There may be others, but I don't know of any. Single lever triggers
have to be set to fire the gun because only the rear trigger has a blade to engage the sear arm. I don't know for sure what kind your rifle has, but chances are pretty good it has the double lever type because these are the most common. Of the old rifles I have personally examined, the reverse is true... Most of them have single lever double set triggers, and their locks typically had no half-cock notch in the tumbler. The hammer could only be fully down or at full cock, and it could only be cocked when the triggers were set, and the gun could only be fired with the triggers set. Modern blackpowder shooters would consider this unsafe, as the half-cock position is the "safety" on a sidelock muzzleloader, but the old timers had a different way of looking at things.
Be safe!
