ok instead of using your index finger and the one next to it to pull the trigger, use the next one in and the one alongside that so that as you hold your gun in your right hand your index finger is not on the trigger but above it. This will give you a far quicker trigger pull on a double trigger mech frame. If in doubt look a couple of years back at what nearly every pro shot their gun like- almost exclusively you'll see this technique being used- i believe it has something to do with the tendons in the hand. For me it was certainly easier and quicker to send long strings using this technique- experiment see what you like
