Guys just wanted to update. I went with the Burris FF3 3 MOA dot. It should be here in a few days.
I am still trying to decide if I am going to mount it on my 870 20 gauge or wait and mount it on the 935.
The 20 shoots dead on with the factory beads and Federal HWT 6's and H13 #6's, but it is pretty tight.
The 935 will be running Nitro's sometimes and old Federal lead sometimes probably both from SumToy chokes.
Which would you mount it on?
