The 356TSW is an obsolete round for obsolete magazine readers. You would do much better with the 357 Sig. Get current! You're missing out on all kinds of good things by keeping your thinking in the 80's.
I shot my new obsolete 45-70 today and enjoyed it greatly. Why? Because I can and I like it.
what would be the point of all of them anyways? wouldn't .45ACP or 9mm get it done, just maybe not as fast... the simplicity of prevalent ammo should trump here, especially considering the amount of time spent training with the same load
