I grew up frequently using my father's Model 12 Winchester and still shoot pumpguns better than most. I currently have a representive pump from each Remington, Winchester (though it's a 1300 - not nearly as nice as the 12), and a Mossberg. The Remington is the 870 in 12 gauge while the 1300 and the 500 are both in 20.
And if it's not bad enough that the Mossberg was just recently added I also happened on a nice Model 37 Featherweight 16 gauge that very same day. It'll likely be in my safe well before the end of the month.

P.S. We let our little brother have Dad's Model 12 but I own and still use my Dad's Model 141 chambered in .35 Remington. Just something about pumps get in your system.
