Mossberg 500! Ya, dad bought me one in 20 gauge. I still have a couple of the Remington Power Piston 3" #7 1/2s lay around somewhere that came with gun. After a couple of years I took it over to Waseca and had Herter's put a nice ventilated rib on the barrel. Then shot it so much I wore out the pin that the locking bolt pivots on. I couldn't get one in time for the duck opener, so I bought a Browning a-5 20 gauge Magnum(still have it). If memory serves me that was a roll pin, perhaps they are solid now, I don't know. The 500 went down the road when I got it repaired. I now have dad's Winchester Model 12 built in 1925. His old hunting partner George (who came back from WWII pretty shot up) carried a Browning A-5 12 gauge w/o rib. Round knob. It was a very nice gun. That probably influenced my purchase. Uncle Bill had a Stevens double 12 gauge from the 1920s, Grandpa Frank shot a Remington Model of 1910 12 gauge, Grandpa Clyde had one of those German Mauser bolt actions in 16 gauge Geka or something like that and Uncle Roger caried a Winchester Model 12 3" Duck Gun.
My gun problem began shortly after a fellow named Buzz moved to town. Somehow we got hooked up and started hunting together. He was a Browning sales representative for the midwest and wouldn't let the Mossberg in the car. So, I got to pick from his 'samples'. I sure miss that Superposed Superlight 20 gauge that he had.
