I plan to buy a full sized 9mm M&P with regular (non-night) sights and NO magazine disconnect at the Houston Gun Collector's show next weekend. What is the gun show price range for these guns? Are they readily available, or should I buy one from an on-line retailer like Bud's Guns? The price from Bud's, by the time it was shipped and FFLed would be about $450 or $460. I'd have to pay Texas sales taxes at the show or 8%. Thanks for your help.
