Ok, so I bought a Beretta A400 extreme plus today as an upgrade from my 870. So here are the questions. What chokes have you found to perform best in this gun? I'm considering jebs, Indian creek, sumtoy, or Rob Roberts. Also llooked at a Patternmaster code black today as well. I will be shooting 3.5 inch federal #9 TSS. Now for the second question. It is already drilled and tapped for optics, and I will be mounting a picatinny rail on it to attach my aimpoint red dot. I'd like to make this a do all gun- turkeys in the spring, and a wing shooter for dove and duck season. My plan is to simply remove the optic and rail after each spring, and remount it prior to the next turkey season. Will this yearly removal and reattachment wear out the threads in the tapped holes over time, to where it will not hold the rail securely? Just curious, thanks.
