My two main points with 2.4:
The Colt 1917 sight has the same problem I've often seen in FH2 iron sights. The top tip of the foresight should be lined up perfectly with the top of the rear sight, not hanging far above it. Right now, IRL, you'd be shooting over the head of all your targets.
And same notation on the tripod mounted 1919, at least the couple I saw. Oddly, the 1919A6 is perfect.
