Difference between 930 and 930 SPX?

[SKILCZ]

I know the ghost ring sights, rail, and mag extension are different. Anything else different between the 930 18.5" with the bead sight and the 930 SPX?

Also, anyone buy the 18.5" / 28" VR combo and shoot trap with it? Wondering how it handles clays.

I shoot Skeet & Sporting Clays with my 930's and the 28" barrels.

The guns cycles the Remington 7/8 oz. Remington "Game and Target", #7 or #7-1/2 shot, 1390 fps with no problems at all....
