Update:
The only complaint I've heard about this mod is the button coming loose.
If the button is screwed in too far, the contact won't touch the battery.
If it is screwed out too far, everything is loose and will come apart easily.
So I decided to fool with mine, as it's not something I wanna have to worry about coming apart.
My first try was some blue loctite paste.
It comes in a stick, like a glue stick.
I put a small dab on a couple of the threads.
Put it together and it seemed all was well.
Later that day, I started having some odd misfires.
It seemed as if I had to hit the button at a weird angle to get it to fire sometimes.
It was really hit and miss.
Seemed to misfire about 10% of the time.
I thought I may have had the depth of the button a little too far in and it wasn't making good battery contact.
So then I looked to my battery.
Thought maybe that some of my batteries had an odd profile and werent hitting right.
Changing batteries didn't really seem to help.
So today at work, I decided to fool with it for a minute.
Took the switch apart and decided to use some regular blue loctite instead of the paste stick.
Put a very small dot on the threads and reassembled.
This time I didn't set the button so deep, hoping the pin would make contact further towards the battery.
It did make more solid contact with this depth setting, but the mod wouldn't fire at all.
I changed batteries, no fire.
Changed atty, no fire.
Took it apart again. Decided to really take a close look at everything.
Cleaned all the loctite out of both sides.
Button and contact.
Looking inside of the threaded portion of the contact assembly, it became apparent to me what needs to be done.
The issue is that the contact threads are too deep, and when you screw the switch into it, there is nothing for it to bottom out on. Hence why it becomes loose so easily.
If you use loctite, it kills the conductivity between the button and the battery contact. Which is why mine stopped firing after using liquid loctite.
The fix is to put something in the female threaded part of the assembly for the switch post to be tightened against.
I decided that a ball bearing would be perfect, as I had a bunch on hand at work.
Ideally a small rod of copper or brass would work great as well.
I decided to use a 1/8" bearing.
Put it in the female threaded side of the contact, then screwed the switch into it.
This worked perfect.
It took up a perfect amount of space for the switch to tighten against.
Now no loctite is really needed.
And if you do decide to use loctite, the circuit will still be conducted between the switch post and the ball bearing to the contact.
The 1/8" bearing sets the throw perfect.
It's deep enough that it doesnt weeble wooble, and far out enough that it will make solid battery contact.
I swear it even hits harder now.
Anyways, for any of you having switch issues, give this a shot.
