1) HEAVY
2) Kicks like a mule
3) No real advantage over a 12 gauge 31/2" unless your shooting reloads 
    or Nitros
4) With the long barrel the gun balances better as a waterfowling piece, as 
    opposed to a turkey gun
 
As a 10 gauge affectionato, I always said if someone make a 10 gauge pump, "I'll have one."  They made the BPS, I bought one, I hunted with it, I sold it, enough said!!!
