I realize this is an old thread, but I just received my new sp 101 in 327 federal, with the 4" barrel Monday, and sent it back to Ruger today, Wednesday, not for sticky extraction, but the trigger would stick in rearward position when shooting in single action mode, never tried in double action, the hammer pull was extremely hard and felt like it was binding, I would have to put my thumb behind the hammer and push the trigger forward to disarm , all it would take is a slight push the it would move forward freely, or loosely, like nothing was behind it, once fully forward it would reset, I disassembled and cleaned went back to the range and same thing, it seems to function fine when unloaded and dry firing, in double or single action, called ruger and they wanted me to send back immediately, so I did, anyone else experience this , my gp100 and super redhawk, or my blackhawk, haven't had any problems. Just wondering about quality of the sp 101 in 327 federal.
