Got to say that you did buy a "classic" and my compliments at that. The Virginian is correct. Did not really have to come this way or converted. Going to be a bit challenging but you may want to buy a new trigger group. I use to have two trigger groups for my 12Ga. One was a shotgun group and the other had a trigger job when switching over to a to a scoped, rifled slug gun. The trigger groups is very easy to remove and install. Good luck and;It is not your imagination. That does not look like a Remington factory installed trigger group.
