What is the bottom line on trigger groups for this model not being reliable, they cost a lot of money but this one won't go bang, bang, two times in a row. Use, release/release or pull/pull, single release and you won't finish the station, I am not posting to complain, just to be educated. This one has been cleaned, machined, reparted and still unreliable x three. My last question is, who is the man to send it to. Love it to much to pass it on, Dick H.
