Okay, let me star off by saying that I love my Paramilitary 2. It's an awesome knife(like I need to tell you guys that.). But I have had it for about 6 months now and its sticky lock was really starting to bug me. I tried numerous times to rotate my stop pin, I played with frame and pivot screw tension. Nothing worked. So I decided to take it apart and check out the internals to see if I could address the problem. It seems to be kind of hit or miss when it comes to this issue, which I though strange considering the cause SHOULD be universal. But anyways, let's get to this issue.
So in my opinion and in examining this lock design very carefully, I found that the issue lies with the stop pin. If you look closely at it, it has machining marks on it that run perpendicular to the way the lock interfaces. This causes the lockbar to get caught in these tiny little "valleys" that resulted from the manufacture of the stop pin. So what we need to do is smooth those little buggers out.
The way I accomplished this was with some 1500 grit sandpaper. I don't suggest using anything courser than that because you could take off too much metal, causing the lockbar to move WAY over. And therefore prematurely wear out your lockup. 1500 grit OR higher. Light, even strokes, grabbing the pin at both ends and moving it perpendicular to the machine lines. I did this around the whole pin, but if you want to try it in one spot, and align it perfectly at reassembly, I suppose that would work too.
So after my reassembly, I flicked my Para 2 open and closed a few times, and BOOM! No sticky lock!
If you decide to try this, please report back and tell us all if it did, or did not work for you.
