M-21 16 ga. field grade. Bought 20 years ago with a non-original 13" stock. Restocked with straight grip, high comb and cast-off to fit, beavertail worked down to a long splinter, 28" tubes opened to skeet 1 & 2. At 6-3/4 lbs. this gun is just right for me, mostly with 1-1/8 oz. pheasant loads and fine with 1-1/4 oz. for wild-flushing late season birds.
