i dont believe the k101 is able to be converted to a magnetic switch. of course, i could be wrong. haha. but i have the k100 and the way the firing switch is configured, its more or less one piece. unless the k101 has a different switch, i'd say no. if youre looking for a magnetic switch, might as well go with a magneto or a nemesis and convert the neme.
but, i must say, my firing switch on my k100 is one of my favorites as far as reliablity and ease. ive never had a misfire, and its really easy to fire. i can stand it on its firing button without locking it and its stable and wont fire. also, youre able to adjust the throw of the switch to your liking.
as far as your kick question, ive never used a kick. (dont feel the need for it for a mech mod) but thats imo. anyway, ive heard of people stating that their kick gets stuck in their k100 or k101 due to the inner diameter of the telescoping tube being too small. again, this is just my understanding from reading on this forum. i have never personally attempted this myself.
hope this helps!
