For me it's the 12 ga. High Standard Flite King. Mine's the very first gun I ever purchased brand new back in Nov. 1968. Still got it and that pump action still works like it's running on ball bearings. But then my circa 1987 12 ga. 870 SPECIAL PURPOSE DEER is also on my favorite list. Lost track of the amount of venison that thing has harvested since 1987 not only by me but by a brother-in-law and a nephew too. Been running a fully rifled barrel since 2001, been drilled and tapped for scope since mid-90's and got a trigger job a couple years ago. But there's another favorite that I never had. An Ithaca mod. 37 Deerslayer; back in the smoothbore slug gun days I wanted one so badly but couldn't swing it back then. Now I'm kicking myself for walking past two nice looking ones on the same table recently at a gun show. Maybe I'll get one next time if the condition & price are both nice. So what if I get one 40-something years after I first started drooling over them; better late than never.
