Does the job, but...
Improves and lightens pull, but... the mainspring doesn't have enough power to consistently fire off anything but sensitive (ie, Federal) primers. Using Remington and Winchester primers, the rounds would only go off about 80% of the time fired double action... probably 95% of the time fired single action. I even had a couple Federals that failed to fire. This wasn't a big deal in the days when you could pick and choose your brand of primers, but that's not possible anymore, at least in my neck of the woods. I've switched back to the stock mainspring for reliability reasons, even for a target gun.
