Glad to hear it worked out for you. Which size did you use?
I bought these o-rings from Amazon. The link was from someone else earlier in this thread. They work great!
I didn’t like those 3D printed diffusers made for the FW3A, so I looked around and found a 25.4mm one by Nitecore that fits perfectly. A good snug fit that is nicely secure.
Installed the aqua GITD optic insert. It’s an attractive color, but unfortunately doesn’t radiate as long as the green one. The saturation below is a bit washed out in the photo, but in person it’s richer. The stainless steel bezel is nicely finished, worth the $4 USD.
I was thinking of ordering this from Amazon but will try to find some local store. Even though it does not costs much, I hate to waste the remaining 99 and them taking space in my already overflowing drawer!
With the o ring my still accidentally turned on. I wish the o ring would give was just a tiny bit more firmness
Think of it this way:
When you trip and spill 99 of them on the floor, you won’t have to bend down, because there will still be one in the bag! :disappointed:
Did you remove the nubbin? Adding the o-ring without removing the nubbin doesn’t help.
Still… even with the o-ring mod there is still a risk of accidental activation. If you want to reduce the risk further you might want to try gluing a washer on the end of the light in addition to the o-ring mod.
Ah yes that explains it, it feels totally different now. When you say washer do you mean externally? I don’t want to add to it’s bulk, any other easy mod inside to help this?
I just did the washer mod for the switch on my FW3T and the difference seems like night and day. It is stiffer and seems clicky now. I can’t wait to see if it helps with accidental activations.
For the GITD insert, I started with the green. I liked the tint of the aqua better, so I got it. It looks nice, but it’s not as bright as the green. I took some photos. And actually, the photos make the aqua appear a little brighter than it is. Green is noticeably more radiant.
Approx. 3 hours later, it’s obvious green is still better. The aqua is still visible, barely. But both relative to tritium are dimmer.
Got some O-rings and modded two of my three FW3As. The third one has the original (and greatest) switch and with the O-ring it is way too firm.
I notice that the O-ring switches are a little bouncy now: sometimes clicking four times to lock out puts it in momentary mode (five clicks) instead. Putting it in momentary mode, I can see that occasionally it bounces when I release the switch.
I’m still carrying it with the O-ring and trying to slow down and be more deliberate about locking/unlocking. Because it’s way better than the unmodified switch. But the bounciness may eventually cause me to reinstall the nubbin.
Bounciness sounds like preload to me. Make sure the o-ring slid/squeezed out of place. Disassemble and reinstall if you haven’t already. Good luck!
Hi folks,
Thinking about a swap to SW45k 219b.
Stupid question:
Does the 219c stock version already have the 50% FET Firmware flashed from factory?
Or do I need to reflash when swapping the 219c for a 219b?
Thx
I’m pretty sure it does not have the reduced FET firmware from the factory.
I’m planning to swap 219B into some of mine and will be flashing the firmware as I go.
Hmm, it’s centered around the circle where the nubbin used to be. In addition to the bounciness what has bothered me more after more use is sometimes it clicks but doesn’t activate the light.
This is with the 3/16” ID; I might try to track down some 5/32” and try those, because I love the feel. But, it needs to turn on every time I click it.
Very cool! Which reflector did you utilize in this? More pics? Beamshots? Are we there yet? LOL
Wow, nice work grin 
Thanks Woke at 2.30am and couldnt sleep so I went out to the lathe. It is a bit rough and i dont have oring for the bezel. Kaidomain reflector 38mm diameter 42mm deep, I put a 1mm2 osram in it that was sitting on my table but turned angry blue on turbo so I put xpl hi in.
Lots of great info here! I did the oring tailcap mod and am very happy with the new stiffer feel.
I ordered a new pocket clip made for a HDS, looks at though it’s gonna be a perfect fit. I’ll report back when it arrives.
Did the DarkSucks clip fit?
