Well, it depends. The take up or slack is kind of long and some feel it's gritty. The actual sear break usually has very little creep and is crisp, but heavy at about 6.5lbs.
The grittyness can usually be eliminated with some 600 grit sand paper and 5 minutes of elbow grease.
There are 2 different trigger types so far as I can tell new ones made after 1-1-14 have the new shield type trigger with the trigger it has a reset you can hear and feel, the trigger is great I feel I don't need a apex job like I did on my others, and mine is the Mass. trigger
The MP9 I purchased was gritty and I was ready to buy the apex but after working the trigger for a night and a half it is much better. If I had to guess the weight I would say about 6.5#. I may still buy the apex but not sure, the trigger is about a C+ or B- in my book.
