I had problems with my k-22 (later designated model 17). Misfires and cylinder binding. Both were resolved with endshake bearings and a new mainspring, but if you want a revolver that just keeps working... I'd go with the SP101.
I'm not a big fan of SA revolvers. To me DA holds the greater advantage in shooting and SD. That being said the Single 10/6 is fun to shoot. I had one in my younger days and it was a fun plinker. Killed a lot of small game with my old Single Six.
Gun permit?? A bread crumb tossed to a sleeping society awoken by the sound of complacency. "They are for your own good", and "you will understand when you see all the lives they save". Yes master, what else will you toss me from your bag of infringements?? Do you want me to roll over and play dead? I do that very well. --skidder
