Sorry to hear all the bad news reports from shady deals done by even shadier dealers- The only 3 gun dealers I ever dealt with, over the past 30 years were: Bill Jaqua, Brad Bachelder and Don Criswell. The only "shady" dealer I ever encountered was about 12 years ago, at a weekend gun show in Lansing. He had a nice looking Ithaca 4E 20 bore, dt, fancy stock, sunburst pad-- I asked him If I could handle it-believe he was asking something North of $3K for it-- I always carry a pocket sized Stanley tape- when I pulled it out to measure the barrel OAL-- he quickly brushed my hand holding the tape rule aside, and said-- _Oh, no need to do that, I already measured them and they are 28" long.
As Ronny Reagan once said: "Trust is fine, but always cut the cards before each deal" I picked it up, measured the barrels at 26&3/4" right on the schnozz-- "Humm, I said, as I handed it back to him-- guess it's time to take my Stanley tape back to Ace Hardware and get it "re-calibrated"-- RWTF
