Still think the Discovery is a perfect pump-fill gun.
After your first fill from zero, the refills (about 800PSI worth...probably the best shooting will be from 1800-1000psi) are a lot less work.
Reading these forums, would get the idea that you have to do the trigger mod...have to recrown...have to have a muzzle brake/LDC...have to add a power adjuster...have to usse only "x" pellets...etc.
Bull.
Buy it, shoot it, and see what she'll do...very good chance you won't "have to" do anything...but if something is still bothering you a month from now, then look into the "gotta dos".
