I also had too much trouble pushing the buttons. However, since I carry it in a fairly solid holster, the last thing I want is for it to activate in the holster and wear out the batteries. My fix, I'm afraid is a little less of an engineering feat. However, it made the push considerably easier, but not too light.

I took the laser out and noticed that both the little nipples were somewhat pointing downward. This probably happened during initial assembly. I also noticed that the foil switches have more play on the top than at the bottom. I simply rotated the rubber plugs 180 degrees in their sockets, reassembled the laser and gun, and now both the switches have the perfect one-hand push to activate.

Before you start melting things, you might just give it a try. What do you have to lose?
