hello i am new to this site and to shotguns i wanted to know which is better to have on a shotgun a ejector or an extractor ? also on a break open single shotgun which parts normally go bad i know the fire pin but i am unaware of any other parts , i am just wondering because i want to buy spare parts to have incase i need them also i want a basic shotgun with less maintenance of parts failing so what that being said would having a shotgun without an ejector be better by having less parts to repair ? thank you in advance .
