No, the gun do not have this special bore. This gun has normal smooth shotgunbarrels.
I googeled the internett to find as much information as possible for my gun. I have not yet tried to search insider the forum as a member. I will give you feedback.
Would you say that code number 34, always would be stamped on the gun if it was made by Sigott in Ferlach, or are you familiar with chases of "named guns" without matchingen number?
Cheers Joar.
