PGP leaking

[sarpadian]

I have a PGP that is now leaking through the gripframe. When you first put a 12 gram in, it will not leak until the first shot is fired. It almost has to be a seal in the valve. I was thinking of buying a PGP/PM1 seal kit and a sheridan valve tool from Palmer. http://www.palmer-pursuit.com/online-catalog/sheridan-parts.htm

Just wanted to be sure I was headed in the right path.
