Please let me know how I can improve my P1A

I have a Klarus P1A. My enjoyment of that light is close to zero because of these issues:

1- Rubber boot is too squishy

2- Clicky is too cheap feeling

Im comparing it to my Fenix LD20 switch and there is no comparison.

So is there anything I can do about the Clicky switch? Can you buy other switches, and how do I know that clicky will be better, or will fit?

Many thanks, I have never modded anything before. Any advice to make the light better I would appreciate it.
