Hello to our new Norwegian friend, from a S&W guy in Columbus where Espen Knutsen plied his trade, if you are familiar with that noteworthy countryman of yours!
and is it made at the performance center?
The Performance Center is somewhat shrouded in mystery... at it's finest, it was a separate building with a free amount of reign to create some daring and amazing models and it was filled with true craftsmen like gun building of days gone by. From roughly 1991 to as late as what, 2011 or thereabouts, the Performance Center did work on some folks' guns sent in, but it was known more for the models they created.
Much is left unknown or not shared. Roy Jinks has said at least once in a factory letter that one of the first tasks undertaken by the then-new Performance Center was to fit and finish and prepare the last examples of the Model 52-2 pistol, and Jinks has also said that they used that 52 experience to develop the Model 952 pistol.
In the days following the eventual closing of the real Performance Center... S&W "branded" the PC name and logo on to production guns with added features or looks. With a sincere attempt not to derail my post with anger and emotion, I'll simply state that the "PC" term added to recent S&W products is a sad eventuality for the legendary name and beautiful PC logo.
Regardless of what S&W offers today, the real "Performance Center" does not exist. It also most certainly did not exist when your (likely early 1970's) Model 41 was built. However, the models 41 and 52 are the closest matches from the 1960's/70's/80's to the fit, feel and potential of guns from the Performance Center.
