Welcome to the site. A very nice gun. Enjoy shooting it. I too suggest shooting it as is for a while and see how you like the gun and decide what chokes you will require. To do this you might think about using spreaders in the right tube. This will open up the right barrel about one choke constriction. I did this with a 12 ga. English gun choked Mod. and Full and liked the performance with a spreader in the right tube so much that I never had the choke opened up. RST carries a 16 ga. spreader in 7/8 oz.
