You've made a wise decision not to shoot it. It is a decoration made to be a conversation piece or a wall hanger.
The writing on the barrel is Spanish and the lock style is called a Miquelet.
The Miquelet lock was a form of flintlock, popular in Spain and a number of other Mediterranean countries.
Unlike a true flintlock, the Miquelet locks mainspring was on the outside of the lock and the hammer was not attached to a 'tumbler' located inside the lock.
The hammer was held in the cocked position by a tab that stuck out of the locks face engaging a notch on the cock (hammer). When the trigger was pulled the tab was pulled back flush with the outer face of the lock.
The Miquelet enjoyed a fairly long popularity with the Spanish but it should be noted that the French, English, German and Americans used the true Flintlock rather than the Miquelet.
The brass barrel band was used by the French (among others) in the mid 1700's. Somewhat later the Americans in the US also used this type of barrel band. In most cases it was used on Military pistols (and muskets).
The shape of the grip isn't much help except to say that prior to 1800 most of the pistols had a more bulbous area at the bottom.
If I had to guess about the time period based on the grip shape I would say early 1800's whether we were speaking of European or American pistols.
I hope this helps.
