The plunger is just shaped wrong from the factory. There is no reason it should be shaped with hard edges to give the trigger the gritty feeling.

No one likes a gritty trigger, but the rest of the complaints w/ the trigger comes down to personal preference. The takeup on the trigger is a bit long and little far back for me and there is not much in terms of tactile reset.

And if you buy the MA version like i did with the 10lb+ trigger, you do you have to do things to it to get it down to an acceptable level of shootability, whether that be a trigger job or putting in apex parts.
