My Gamo Silent cat .177 with lead pellets shoots 597fps. It’s like 10 years old and I’ve never liked it much really. Why is it so slow?

I don't have this rifle but I see the advertised speed is about 1000 fps with lead pellets. I usually take manufacturer's numbers with a grain of salt and I'm guesstimating a more realistic 900 - 950 fps. Since this is an older rifle, about how many pellets have you shot with it and how often have you done maintenance on it (clean the barrel, oil...)

Depending on how much you've shot it over the years, the spring could be wearing out/getting weaker

The spring may be "tired" due to age. The spring may be broken. The piston seal may be too tight. The piston seal may leak. The breech seal may leak. How far into the gun do you want to go? All of the above require disassembly except the breech seal. None are overly expensive if you can do the work yourself.
