I was looking at my 40C the other day and noticed when the trigger was pulled, there was a lot of side to side movement in the trigger bar. It actually changes the location where the loop contacts the sear from shot to shot. Doesn't seem to affect the gun going boom, but I can't help but think if that bar moved in more of a straight line, the trigger would be better. Any ideas?

The trigger bar has to have some slack so the trigger can reset but it's hard to say if there is anything wrong with it without looking at it.

I'm not saying there's really anything wrong with it, it just seems odd to have that much lateral movement.

its not odd if that lateral movement is part of how the gun functions. If i understand the workings of the striker properly, that trigger bar needs to disengage from the sear block in order for the striker to reset after firing. There is a channel cut into the slide that forces that trigger bar laterally, off the sear, as the slide moves rearward. once out from under the sear, the sear is free to pivot again.

if the trigger bar stayed where it was, beneath the sear block, the slide would cycle but since you're still holding the trigger down that sear block would stay down when the slide cycles and it wouldn't catch that lug on the striker as the slide returns to battery, so your striker wouldn't cock back to fire again.
