If your phantom is tuned conservatively (read: you haven't messed with springs, powertubes or hammers) you shouldn't be able to cock it without air. When you pump back, the mainspring overpowers the valve spring, not allowing the hammer to get close enough to the bolt to latch on.

For some reason, I can pump and pull the trigger on mine, even without any CO2. Is this a big problem?
Maybe you have a weak main spring? Or you have a very strong Valve spring?

pretty much. It is sprung funny. Nelsons by default shouldn't cock without air. It isn't a problem if you can. But your springing is funny, so check what you are getting for air efficiency, it might be out of whack...or you might be having to turn your Velocity Adjuster/TPC in more to fight the stonger valve spring/weaker hammer spring, whereas if you had a normal spring job, you'd barely have to turn your TPC in.

I've run the majority of my nelsons this way for over 20 years now,the set up that most nelson freaks have settled on for performance is lapco 34g hammer,lapco #6 powertube,red valve,yellow main oe equivelent. in most setups depending on sear/spring strength this will cock with no air,this combo can be easily adapted to any modern phantom,by purchasing a lapco #6 powertube and cutting it to phantom length or honing a stock phantom powertube wich is a 4 to a 6 wich redux factory can do,shaving/milling/drilling a stock phantom hammer to 34g, with the proper springs your well over 40 shots a 12g.
