Watch yer favorite playoff game with your trigger group in one hand. Take a syringe of grease and apply the lube to the hammer hooks, I show this technique in my clinics.
Then with your opposite thumb over the hammer (don't allow the hammer to strike forward) and your master trigger finger working the trigger, FIRE and re-#### that hammer repeatedly.
Keep doing this throughout all 3 periods of the hockey game. This technique will SMOOTH up your sear and hammer sear engagements (and it's safe to do yourself). CHEAP, too.
