KNS anti rotation pins?

not really needed unless the trigger group is installed wrong, or you want to add the "cool factor".

There is also a version of trigger and hammer pins that have grooves for C clips.  And unless you're actually having problems that are not fixed by correct assembly of the parts, neither KNS pins or C clip'd pins are needed.

When properly installed, one leg of the hammer spring sits in the groove at the end of the trigger pin, holding it in place (with a little wiggle room).  The hammer pin is retained by a "J spring" within the hammer itself; it sits in the groove in the middle of that pin.  It is normal to see both pins move a tiny bit with firing, but for some reason, not everyone understands that, and they go to a lot of trouble and expense fixing something that isn't broken.

If the trigger pin is walking out while shooting, your hammer spring is probably on upside down or the legs of the hammer spring are not on top of the trigger pin.

It's called a hammer spring.  See above post.

Yes it happens. Even with the super duper Geissele FCG's. If you feel the need for KNS pins, don't worry about what purists think.
