Is there a retainer pin for the trigger pin? If not, that's the problem. Kahr should send you a retainer pin and or new trigger pin, which should solve your problem, which would be the best solution. If there is one, it may not be in the groove on the trigger pin. You could talk to Kahr CS and see what they advise. Lastly, I would super glue it.
Kahr has been quick with turnarounds... none longer than a week for me. P380x2 and PM45x3. Last PM45 trip was to replace a replacement DLC slide with a very faint rolled or struck engraving.

Loctite recommends NOT using Loctite on plastic... removal could break your frame. The red requires about 500° F to break a bond and the Green and Blue require chemicals that may damage plastic.

This is assuming you got a GOOD bond and removal is necessary.
