Anyone else think the pump stroke on the undercocking version is extremely smooth? It's probably the smoothest I've felt so far. I'd use the thing if it wasn't in such good shape.

I've actually never used a Hornet, but I've owned multiple Trracers, Mavericks, and the PMI version of the Hornet, the Tagmaster.
I've found that the side-cocking versions of these guns are usually smoother than the undercockers, but that's just my impression.

Smoothness isn't everything, or even that important, and their capacity to keep dirt out of the action is probably more important.
