Mine is a shaved, post war (WW I) civilian model, that I really need to find a round-tuit and send the cylinder off to Doug Guy for a bit of his magic. At present it is not all that accurate, more groups over 4 inches than under, but an fun gun to shoot none the less. Mine suffers from the under-over, throat-barrel relationship common to these. The Throats run about 2 thousandths less than the bore.
