I researched mods for weeks before deciding on a side firing model, but not enough to keep from getting a burned finger from the Kts within first 5 minutes of giving it a try. After searching ECF I found several threads nabout overheated firing button but nothing about if you can use it without the collapsed hot spring as many mods don't have them. Also do you know a sure fix to the issue as sanding contacts doesn't always work as reported by some. All the contact on this one have a gold colored plating, do you know if they're brass underneath? Any help would be appreciated as I in dire need of another working APV as I'm down to only one working model. Thank you for your time.
