I just purchased a Small Pro Deluxe from Bagmaster and would encourage you to not.
It isn't that these aren't well made bags, or that the company isn't great (they were extremely helpful in selecting the right bag for me needs), it's just that the bag isn't well designed, IMNSHO.
There are no mag loops. The interior is one large space broken up two panels that velcro to the sides for adjustment. And the gun pockets are on the long sides. This makes them unnaturally long for the 1911, with lots of wasted room, and not too tall.
Overall, I think this might become a camera bag.
Now I'm looking at spending $165 for a Waller rangebag. The pic in the magazine shows a model that has mag loops, great departmentalization, and some more. Very interesting.
Of course, another option is the cheap plastic toolbox from Lowe's. With your guns and optics in protective cases, you can carry all of you stuff with you and have a handy place to sit when you get there.
