I dont own one but they share a similar action to the BSA guns theyre based on. Id guess you could get around 30-34 fpe if you mod them.
Anyone know if the hammer housing is the same on the Gamos as the BSAs? If it is the same you could order a heavier hammer from John Knibbs. The R-10 hammer and older Scorpion MMC guns had the heaviest. You can also open up the TP port a bit. Im not sure what the Gamo TP measure(they're different item #s on Knibbs) but the R-10s is 5mm or 4.7mm.
Just spit ballin. I know alot of ppl are happy with them the way they are so you may not need to do much more then increase the HST and find the sweet spot and keep the gun within it's limits.
