Cant help on the older SP101-22 but my new 8 shot is a wonderful revolver. Its very accurate. Its a beautiful gun, fit and finish is perfect. I have had a few issues with extraction, sometimes the ejection rod feels like its jammed, but a light rap with my plastic hammer on the end of the rod, frees things up. It may just be a couple empty cases are stuck in the cylinder. This does happen from time to time with rimfire. My barrel is slightly canted, making the rear sight to have to be adjusted off center slightly, but its not a big deal. It will shoot all 8 shots into 2" at 25 yards rested. The trigger was pretty heavy in Double Action when I got it. I experimented with reduced power Wolff springs, and couldnt get 100% reliability with any of the lighter mainsprings. I eventually went back to the original rimfire mainspring, but used the Wolff 8# trigger return spring. This helped alot, and I now have maybe 2000 rounds through my SP101-22 and the trigger is much better. If you have your eye on a SP101-22, dont wait too long to buy it. They are hard to find, and dont last long in the gun shops.
