I was on the fence with this too. One of the posters said something like 'try it, if you don't like it, you can sell it"
Made sense to me so I ordered the Apex enhanced V2 flat trigger and haven't looked back. Trigger is a little lighter (don't have a gage) but not enough to go off without a deliberate pull.
It certainly isn't a target trigger. I'm thinking I should have polished the contact points a little better, (I can feel a little 'for lack of a better term' "grit' or slight lack of smoothness til it gets to the break, but then it's crisp and decisive (to me anyway).
If you're using for EDC you're not going to notice it should you need the gun for protection. How the trigger feels will never enter your mind at that time.
Reset is same as original trigger. No double click. My groups are a little better with the Apex than the original sig curved trigger and that's what I wanted.
Probably just me, but I couldn't get the 'tool less' instructions to work when putting the spring back in. After the 6th try I resorted to the needle nose pliers and all went well then.
