I believe the nose of the hammers is too short, and it leaves a wide gape between the hammers and the firing pins. With the wide gape it almost leaves the impression of a non-rebounding lock at half cock.

I'll have to endorse the statement above, that instead of spending $75k+ on one of these I would rather have three or four vintage guns in good high condition for the same money.

JMHO, as always.
