Don't change a thing! It's perfect as is!
I feel like the compression lock is really what defines it as the para-military, changing the lock would turn it into something different.
My only beef with it so far has been with the pocket clip, on my CF and regular production models, the pocket clip screws have come loose repeatedly, I think the diameter of the holes on the clip itself are slightly too large, the screw head is what seems to be creating the friction holding the clip tight rather than the screw shaft. I've had to really tighten them down and loc-tite them in place to keep the clips from moving side-to-side, my others have not had this issue. Last time I used loc-tite some of it dripped down and gummed up the pivot so I was forced to disassemble them and clean out the extra. At least they disassemble super-easy. Anyone else experienced this issue with the pocket clips?
I think I prefer the style of clip on the para-military 1, I like that the pivot screw can be accessed without removing the clip when in the tip-down configuration.
