30 or 32 inch barrels are better but get a gun that you feel comfortable with preferebly a multi choke that way the more experience you get shooting it the tighter chokes you can put in the ideal chokes to start with would be 1/4 & 1/2 that way the moore confident you get you can tighten up on your chokes.I shoot a miroku 3800 grd3 32 inch 3/4 & full at everything but that has come with years of experience.
