I got a Remington 870 Tactical for Christmas. 18" barrel with a 6 shot tube. I have had one of these in the past and unfortunately it was lost. Before I lost it, I had put the Magpul SGA stock and MOE fore-grip on the shotgun and loved the way it felt. I will be doing this again. There was a TacStar 6 shot side saddle on the old gun and it seemed to work okay. I think if I were to get another side saddle I would get the Mesa Tactical saddle. My dilemma right now is deciding on going with the side saddle again or getting shotgun cards. I like the idea of having a card that holds 6 or 7 shells like the Esstac from SKD. It seems like for the price of the TacStar side saddle I can get 2 Esstac cards or for the price of the Mesa Tactical side saddle I can get 4 Esstac cards. Looking for opinions from those that have used both OR a shotgun card exclusively. Doesn't have to be Esstac, I know SOE makes cards too. Thanks for the input SET!
