I like the lock design and how slicey the PM2 is, but I tend not to carry it as my primary knife due to concerns on the strength of tip. The 940 got a fair bit of pocket time earlier in my knife collecting, and I think it is still a great EDC. I have carried and used a lot of Axis lock knives without any spring breakage, but I understand the concern.
Honestly, if you are ok with a bit more deliberate closing effort, the Spyderco Gayle Bradley 2 is a heck of a knife in the same price range. The hollow grind makes it very slicey, but the M4 steel and overall design carries a lot more strength to the tip than PM2. It isn't stainless, and some folks don't like the liner lock, but it is definitely a knife I trust as a solo EDC.
