The six up has a middle piece that comes out, so if you only take four handguns, you can lock some ammo or whatever in that spot.
I don't have the 925, but have the 6 up 935 and the quality is impressive. With shipping and tax I was all in for $266 and am very happy with it for the price. Very convenient for hauling pistols to the range with generous spacing between pistols for trigger locks.
