The DAK trigger is a nice design, it gives you a consistent trigger pull through the whole mag. Some people like it and some dont. I like Sig steel and alloy framed DAK's because there can be a lot of deburring and trigger work done to make them much smoother, but not so on the 250.
As far as possible scenario's goes.....im not sure what you mean.
Look at the DAK this way, it is similar to glock and springers striker-fired guns except you still have re-strike capability. The trigger system is not why i dont like the 250, it is more of the horrible, heavy, gritty trigger pull and in that category of pistol, you can group HK's LEM trigger, which imo is much more superior. But a 226,229,220 DAK with trigger work is FAR FAR superior to the LEM system
