K11 or K31
Hi,
The Swiss straight pull rifles evolved with respect to the bolt design even though they look similar externally.
The fist versions 1989 had the locking lugs on the "bolt carrier", not the bolt itself. Weakest Desgin.
The K11 located the locking lugs on the "rear" of the bolt. Better Design.
The K31 located the locking lugs on the "front" of the bolt. Best design.
If you want one to shoot, the K11 or K31 os OK, with the K31 being the better choice. I would leave the 1891 for use as a study piece and a "wall hanger".
Cheers !!!!!!
