I have never had a problem switching front to rear or rear to front on the triggers. Which ever I start with I automatically go to the other.

I had a similar problem with a 20 ga. Spanish gun choked full and fuller, so I had it opened to skeet and IC for skeet shooting. In retrospect I should have had a set of screw in chokes put in because the pattern is rather thin for hunting beyond 20 yards.

Good luck.
