Like I said depends on Terrain..... 50 Yards and under or up to 500 Yard encounters? Big difference.....
SMG's in 9x19 obviously have a limitation as JTV mentioned. But the Hungarian Kiraly 43M inStG 44 or Suomi M/31. I have only shot StG once, but it felt surprisingly similar to AK, which I am very familiar with and while controls differ they are not that difficult to learn. I am very familiar with Suomi M/31, but nowadays 9 x 19 could be a problematic choice if facing opponents with body armour. In some conditions also PPS-43 would suffice very well considering how handy and light-weight it is.
Preferred pistol would be either FN HP or 1911 - both of them work for the purpose.
That is interesting Patrick. I just came into owning my first Carcano carbine very recently, a 1938 and I feel it is such a neat little carbine. My problem is that our weather has been horrible and it took a while for my new range membership card to arrive. Cold enough to freeze the balls off a brass monkey this weekend so it will be a while yet.I will go off the rails with a Moschetto Modello 1938 in 6,5x52 mm ... to me it is a simple, easy to use rifle, many do not like Carcano's but to me I can shoot them very well and load them rapidly when needed.
I also would be comfortable with a Fusil a Répétition de 7,5mm Modèle 1936, another simple, easy to use designed rifle.
Re "...well 6.5mm is a nicer round than 30-06." Ain't that the truth! I like the Garand, and I like 6.5x55, so when Criterion made a 6.5x55 barrel for the Garand, I jumped at it.
as for a WW2 rifle, well 6.5mm is a nicer round than 30-06 and if STG44 was not a choice then a AG42
IF it were only that easy...My neighbor who was declared 4-F twice and after a third time being called up, figured it a cinch he'd be turned down again...Even though he was legally blind in one eye, he was taken as Selective Service needed numbers in 1943....His MOS was Carpenter and so he was detailed to building Bailey Bridges....I would not go into battle. I would be 4F,& take care of the women and protect them on the home front! some body has to do it! LOL!
