Sheridan H9 .20 cal Pistol??????

I was wondering if there are any upgrade kits available or rebuild kits for it?

i dont know if there are, but if the problem is holding air......take all the seals out, and put some Crosman pellgun oil on it. Whatever is in that stuff, makes it amazing, its known to fix seals.
