Just curious, have you played the Borderlands games? Because I have the same issue with some of the guns in those, as well. It’s actually a common problem in FPS games in general.
In the Borderlands games, I do a LOT of farming for better gear. For example, in BL: The Pre-Sequel, I am farming the BEJEEZUS out of the Titan Robot Production Facility right now! When I’m doing farming runs, I’ll set a nice, small pistol in one of my equipped slots, and switch to it whenever there’s no enemies around, so that my field of view is larger.
The only problem with Battleborn is that it seems you won’t be able to give Oscar Mike a smaller sidearm.
