If it's in freshly unboxed, wall-hanging collector's condition, I would. A great piece, plus a bit of back story.
More realistically, they tend to be pretty beat up, full of crud, and rarely cleaned or lubricated. I've seen 'fairly new' police trade-ins on the rack in worse condition than four generations of hunters have done.
My friend bought a police trade-in Winchester 1200, and it had bluing worn, gouges in the receiver, had never seen solvent in the barrel, had literally about a quarter-cup of dust/unburned powder/dirt-mixed-with-oil crud in the inside, which we only found out about after the (I kid you not) the pebble inside the receiver worked into the trigger group and locked it up.
And that was the best one on the rack!
Fridge logic on the pebble problem: this had apparently come straight from a cruiser trunk or armory to the rack. What if it had been pressed into use in that shape? Bad juju.
