Need to know if it is a derringer or rifle.
Put hammer on half-cock and & push rear of barrel to the right.
No
I'm afraid that is like asking, "Does a car have a tape player?" It depends on the make and model. Personally, I have a Colt .22 Model 3 derringer and it does NOT have a safety. But, I cannot speak to the many other makes and models.
You need to leave this to a good gunsmith.
no, just 45 long colt, what is was made for
