Two of the three that I have experience with can be field stripped easily, by just lining up the marks and pushing the slide stop pin out with the pointy corner of the magazine. The other one, an older K-9, has no marks to line up, so I just guess where to hold it, and the pin has to be tapped out with a screwdriver handle or a little plastic mallet. No big deal on any of them.
They are tight, when new, but after about a dozen take-downs, they loosen up a little, and you get the hang of it. Nothing to be afraid of.
