Not true. The 11 pound plus trigger pull on a G43 has been reported by a number of people. I looked at two of them at the gun dealer (the display model and the one I purchased) and they both had the same trigger pull.
But, I suppose the two I looked at plus a number of others reported in forums by other people could all be defective. In which case, Glock has a real quality control problem.
Instead of making excuses for Glock, just accept the fact that the G43 trigger is awful.
When the G43 was introduced, it did have a heavier trigger pull. I don't have a trigger pull gauge, but my early model was easily 8 plus pounds.
They modified the G43 connector on later and current production, so the trigger pulls on these should be in the same range as the other models. I replaced the connector on mine with the updated one, it is good to go now. Which is to say, just because you got one with a heavy pull doesn't mean they are all like that. Maybe yours is one of the early production examples.
