Got this in the week.....
The tension on the ball detent was way too strong resulting in the blade being very hard to deploy.
....sooooo I broke out the Dremel & tools for some PM2 pimping.
Modified the detent blade tension, mirror polished the brass spacers & contact areas on blade pivot and liners.
Lightly lubed with Fluid Film on friction areas - put it back together and walla....the most supersmooth Para ever.
Now to get rid of that ugly edge....
