I went into a local gun shop looking for a side saddle for my Mossberg 500. I've done a little research on both TacStar & Mesa Tactical side saddles. Two obvious differences b/t the two that I've noticed, was that TacStar is polymer w/ an aluminum backplate & retails for around $30, where as the Mesa Tactical version is all aluminum & retails for around $60. I assumed that an all aluminum side saddle would essentially be more durable than a polymer side saddle. I asked for the Mesa Tactical version, and the guy there looked puzzled when I asked him about it. Oddly enough, he had never heard of it, neither did they carry it. They did have the TacStar version though, so that's the one I went with. Did I make a bad choice in choosing to purchase the TacStar???
