I don't care for the handle of the 520. It grips great in the hand (which is good) but it grips great in the pocket also (like pulling a cheese grater out). I have a 520sbk that I am trying to sell on the For Sale forum. Not trying to push a sale but my asking price is way lower than $170.
Now I love the Axis lock, my preference is either a 710 or 615. Both fit my hand great and carry like a dream. The Kulgera is also another nice axis lock.
I also have no experience with the Microtech.
