Recently I found an old model 6p that has a tape switch that's in pretty sorry shape and doesn't work the greatest. I'd like to replace it with a regular momentary switch. I'm having troubles finding a z41 switch for a reasonable price though. The only two options I have found would be to buy either a G2 tailcap or an aluminum tailcap from solar force. Would either of those options work well? The solar force looks like a good deal, but I want to make sure it's absolutely reliable since I'm using this surefire for a gunlight. Thanks.
