I like the trigger. It is not a lot different from the trigger system Tom Burgess made up for the Brno ZKK series. An issue I had with one 550 trigger was that it could not be set very heavy. About 2 1/2 pounds was as high as it could be set. Otherwise, it would not reliably re-cock. Strange, I know. The basic design is good. The single set system works very well and, if you like single set triggers, it's a good one. gd
