Amen to the last two gents who posted re: "The Perfect repeater" I own 7 at present- mfg. dating from 1921 to 1949, and I shoot all of them that are in 12 gauge (5 including the 3" Heavy Duck) on a regular and steady basis. I would field strip the receiver, removing the bolt- you have to push down the trip and pop out the spring ejector stem from it's notch-- sometimes the cartridge cut-off can get slightly bent-but unlikely, as like all the metal parts of a M12, it is made from forged alloy steel, not cheapo steel stampings and or plastic like the current Remington and Mossberg pump guns are--
clean out all the crud in the receiver with the bolt out, check the extractors- they are NOT interchangeable, and are of a different configuration for your 12 than for the "midget gauge guns"--I would also suggest you remove the magazine entirely, check the spring, clean and also the "thimble" cup that the compressed spring pushes forward (reward toward the receiver on an assembled M12) for grit and or any obstructions-- last check- the take-up notch- make sure the set screw has bottomed in place and is not above the receiver/magazine annular ring-- Good shootin' you'll never wear out a Model 12- nor will your great-grandson either!!
