I always wanted a short drilling or "Kurz-Drilling" (as advertised by Krieghoff before WW2 with 55 or even 50cm barrels). After some reluctance my gunsmith finaly did it for me. My beat-up Sauer 7x57R/16/16 from the 1950s now sports 48cm barrels (instead of factory 60cm) and handles and shoots like a song. It came out better than I hoped and quickly became my favorite drilling.
There were no problems with soldering, or any other for that matter.

Kind regards,
Jani
