EDIT Edit: Okay, so while these first few options aren't good for quick reloads/high capcity (compared to other guns), they are fun for having several options on tap with decent capacity for what they are. First up, a semi-modernized, single-action Lemat. With a mini-shotgun barrel underneath and nine chambers, you could have a variety of heavy (pistol) caliber rounds for the purposes you need, with an emergency option if someone gets too close. If you want to go for higher capaity, It's fairly unorthodox, reloading would be a pain (no simple shortcuts in the field), and I don't know if its action could be modernized, but it's also a 20 shot, double barrel revolver. The second barrel in particular lets you choose what you're shooting. I've also seen a triple barrel 30 shot version, but the 20 already looks awkward, and having to reload 30 chambers one by one would be quite a hassle. My top recommendation would probably be to emulate the sginature system of the MP-40/1. It has two magazines side by side. You load two, fire the first, and slide the first magazine to the side so the second can feed when the first is done. Or in your case, when you need to swap ammo types. I wouldn't straight up copy it, but this seems like a decent option. While the weight issues wouldn't be so much of an issue, unlike real life, there is the issue of it being more prone to picking up dirt, dust, debris, etc. It also adds to the maintenance requirements. That said, if you're willing to put in the time, maybe you could dual wield smg's with this setup.
