Advice for getting a firmer switch?

I have the 01 with clicky switches. I’m constantly hitting the enter key when I am trying to hit “h”, which is annoying. I’d like to swap the switch or spring with something firmer than what is there now, to minimize this (I’ve been using the 01 for around a month, and still haven’t learned not to hit the dang enter when hitting “h”!).

Suggestions? I’m competent with a soldering station and have quality soldering and desoldering equipment, so I’m not afraid of swapping entire switches.
