I purchased a "Blurple" Military - and it has some distinctive changes from all my other millies - the larger lanyard hole I get... but I am not understanding the 'stop pin' vs the old 'stop bolt'

I have searched this forum, but I haven't read an explanation of why this is an improvement over my older military models...

I admit my knives biggest opponents are cardboard and zip-ties... but I like the look of the matching bolts all down the handle... why break the symmetry?

(ps this doesn't dampen my enthusiasm for the Military model - I have over 50 of them - and I will continue sneaking the new models into my collection as quickly as I can get them past my wife's nose)
 
Easier blade adjustment I think. Sometimes on my para2's I have to adjust the screw closest to the blade pivot. But that's just guess.
 
I can't find where I read it, but I'm certain that I read someplace that the shock of the blade hitting the stop pin would sometimes make the threads come loose over time.

Not sure if that's the case here, but not all changes are made to for CQI. Some, like the switch from rivets to screws as the pivots on unlined FRN models, are made for easy of assembly at the factory.
 
Just me logic-ing my way through the potential reasons for the change. There're two issues regarding stop pins that I imagine the new stepped pin might address. One is more likely than the other.

The first and biggest issue is removing the need for tightening down the frame at the stop pin. One of the more common culprits in the Military (and, I've read in the Paramilitary) of creating blade play or pinching the action. Because the stop pin is so close the pivot, too much tension there can actually bend the frame away from the pivot creating play. Removing the screws means one fewer potential cause of blade play.

The second is ease-of-turn. I'm not sure that the new pin actually addresses this issue, but it may. Stop pins wear over time from the tang hitting them on open. If the pin wears too much, I can create extra space in the travel and potentially create lock up issues. A free-floating pin eliminates this issue by being able to turn, so the same part isn't taking the hit, so to speak, every time. The stop pin in the CQI Military, however, is seated pretty tightly, so I'm not sure it could be called free-floating.

When you simplify something it's less prone to failure, a solid pin has very few failure points. I think it goes with the larger hardware and pivot bushing to make the knife more rigid/stronger. Stronger, smoother, faster, more refined... My 52100 military is the best Millie I have ever owned, I think Spyderco did good on the CQI.

Good points Jason, I agree. Mine is also excellent.
 
A several times I received PM2 s that had side to side blade play on lockup that could not be adjusted correctly with the pivot screw. In all cases adjusting the stop pin screws solved the problem. One early sprint run I returned to Spyderco to correct the play. They called me by phone to tell me the play could not be completely adjusted. I tightened the bolt screws very tight on both sides, and the play disappeared and the action remained smooth.
I still wish I had that option with the Military.
By the way, I appreciated that personal phone call from Spyderco customer service. Surprised me.
 
I really dig the CQI changes. If I were to pick between past and current Millies I'd choose the newer ones every time.
