Keep in mind that many adapters/extenders are prone to cause shorts.
One of my three ERAs is perfect and two are out a smidgen bit more than I would like but not as bad as the one in Robert's picture. I'm having to use a shortie 510 adapter on all my Woods. On close inspection of the three new adapters they have more visible insulation around the center pin than the old one I have. Old one I had to raise the center pin on male end which moved the pin to one side. I trust the old one less than the new one but trust in either is not very high.
As all my Woods need 510 adapter I've decided to use extender/adapter only on the VVW, for now, due to it's protection circuit. (Replacing Wood springs requires soldering but Metal springs require only screw.) So I'll stick to the Metal REOs and VVW only for ERA, for now, when I have to use any adapter/extenter as Metal REO springs are easy to replace.
BTW... I did have to raise the center pin slightly on VVW to get it to fire with any of the adapters.
{edit} The male end center pins can be "wobbled" on both but the new one stays more firmly in center position re, it is less "wobbly". I got the new ones at madvapes. I'd be interested to see the extenders from other vendors.
