A shotgun sight is provided with a barrel, a sighting rib, a rib support member, a pitch adjustment mechanism, and a latch mechanism. The rib support member is provided on the barrel. The pitch adjustment mechanism is provided between the rib and the rib support member to adjust pitch of the rib relative to the barrel. The latch mechanism has a pair of coacting base plates. A first base plate is provided along a proximal end of the rib and a second base plate is provided on the rib support member. Each base plate has an array of complementary-shaped interlocking projections. One of the base plates is configured to be forcibly urged apart from the other base plate to reposition the array of interlocking projections in order to selectively position the rib relative to the barrel at one of a plurality of locations each corresponding with a unique pitch for the rib relative to the barrel. An adjustable gun sight is also provided.
