Legitimately just an obscene insurance policy, fast and powerful shutters, and all business being done through 2"-4" thick bullet resistant plexiglass. Running a store like the one in the image (probably jewelry) anywhere near the hood is basically asking for it. You're gonna get robbed and it's going to happen more than once. Build your storefront accordingly so when it does you get the last laugh.

If I absolutely had to defend the place with force instead of calling them exactly what they are and laughing as they get angrier and angrier through a near impervious amount of acrylic then probably the most reliable magazine fed shotgun I can find loaded with 00 buck. Alternatively an AR pistol with 40 round mags full of frangible ammo.
