Like I mentioned earlier, this is the first time I've heard this mentioned. I will have to look back through this post. Not sure what Rob charges nowadays but I think when I had one done it was like $20 + shipping, but that was well over a year ago and I don't have that device anymore.Doesn't anyone else notice how much higher the button sits? I have seen plenty of people comment about it here.
What does Rob charge now for the whole 510 update and rebuild deal now? I am curious. I would send mine in for the update, even though I don't care about the 510, I just want the longer throw.
The only suggestions I can think of have already been mentioned. 1. Try going with a flat top battery.
2. If you have the old firing pin in your device, maybe swap it out for the newer B.C. pin that is rolled over on the tip as opposed to just being bent.
3. Maybe replace your button with the newer heat resistant button that Rob now uses. Maybe it is slightly longer... Not sure!!
