The 935 wass designed to shoot 3" & 3-1/2" loads and the barrel is over-bored to a 10GA diameter that help produce better patterns when using steel shot. Some folks have been able to get their 935's to shoot 2-3/4" shells, but I believe thay have to be 1-1/8 oz or heavier in order to get the gun to cycle reliably.
The 930 (my favorite) is designed to shoot 2-3/4" & 3" shells, I have yet to find a commercial shell that my 930 wouldn't cycle.... very easy to take down and clean, too.
If you want to use the gun for shooting targets and hunting the 930 will fit the bill better than the 935.
If all you want to use the gun for is duck or goose hunting and plan on using those 3-1/2" thumpers, then the 935 would be the gun to look at.
Mossberg sells this 930 Field / Security Combo that comes with a 28" barrel for shooting targets and hunting & an 18-1/2" barrel for when you have it in the bedroom:

Also, If I get the 930/935, it will most likely be the "base model" cant afford the SPX. So, whats the aftermarket parts availability for the two? pistol grip stocks, mag tube extensions, sling adapters etc?
All of the accesories you mentioned are available for the 930, and if the fit the 930, they'll fit the 935...
Good luck and let everybody know what you get....
