Impressive pull weight averages!!!
Wow, if you'll note above...I mentioned that the ACT unlike the vast majority of mil spec single stage triggers Ive ever shot, is actually predictable. After reliability, I value predictability secondly. Not only did I hate having to fight the hell out of 9.5lb-10.5lb triggers in my colt 6520s, but even more importantly, there was no way to tell when exactly the shot would break. This by extension made me focus tons of attention on thinking about pulling the trigger and when it would be actually breaking vs. keeping my attention on the target through the sights which is where all my attention should be. A great trigger is one in which you don't even know it's there.
So anyway, I was excited to check the pull weights on this trigger to get some actual data to support the statement I made above that was based purely on the feel of the trigger. I was quite surprised, and impressed with the 10 pull weight numbers. I also wanted to show the effects that properly greasing your contact surfaces will have upon the pull weight. I started of by removing all the grease on the surfaces that I had installed it with, and performed five pulls like that. Then I properly greased the surfaces, and performed another 10 pulls.
First five pull weights w/o trigger grease:
1.) 6.29
2.) 6.61
3.) 6.36
4.) 6.24
5.) 6.33
________
Avg. pull weight: 6.366lbs Standard Deviation: .14363
Ten pull weights w/ trigger grease:
1.) 5.81
2.) 5.85
3.) 5.93
4.) 5.98
5.) 5.76
6.) 5.92
7.) 6.04
8.) 5.74
9.) 5.91
10.) 6.08
__________
Avg. pull weight: 5.902lb. Standard Deviation: 0.11331
I will have to refer back to my notes to be positive on the pull weight averages I recorded on 3 different S2S triggers, but I'm pretty sure that this ACT actually had a lower standard deviation than any of the S2S. Again, that pull weight avg. amount and the low standard deviation in the string is awesome to see.
I'm not sure if a vial of grease will come with these triggers since I didn't receive any, so that is one thing to be aware of.....do yourself a favor and pick up a small amt. of Aeroshell 6 or Mobil 28.
