I've had a couple, a Broadway trap and (my wife's) Diana 20 gauge. Wonderful guns, easy to remove stock for cleaning/lubing, very well made. My Beretta 687 is about 1/4" shorter at the action, but except for being able to see a difference, it doesn't seem to affect handling at all. Fit and finish of Superposeds is wonderful! Forget about using the barrel selector in the heat of a flush.
