Had the opportunity to shoot several interesting weapons:
MP40 — as always, very pleasant to fire but feels entirely too toy-like.
M3A1 “grease gun” — love it, my favorite. Primitive but reliable and controllable.
Stg44 (current semi-auto version) — comfortable to fire, ergonomics are completely awkward. No place for the forward support hand that’s not hot metal.
BAR — uncontrollable hand-held, nice from a bipod.
SW76 — more controllable than I remembered it from a decade ago, but still awkward
Scorpion in 7.65 — the big surprise of the day! Very controllable and comfortable to fire. Can be operated with one hand.
DP27 — my favorite in light machine guns. Fixed barrel doesn’t work as well for sustained fire, but it’s far more controllable and comfortable that MG42, for example. Not sure how it would compare to the Bren. Certainly more friendly to left-handed users.
Suomi K31 — after the PPSh, not very impressive. Ergonomics and controllability inferior to the stamped Russian version.
Romak — nice trigger, low recoil…but theEast-Euro optic on it was wretched.
RPD — the other surprise of the day. After ten rounds, I passed that rattling contraption to the next shooter. Very unpleasant to fire.
All that was improved by the presence of American and German WW2 reenactors, helpful Lucky Gunner staff and many friends.
