I don't discount the 77/97. I am a big Weihrauch fan and if I could only have one rifle a Weihrauch would be it. I do feel like though that the ProSport is much more refined that the HW. The shot cycle is smoother and it is a more efficient designed, exemplified by the lack of preload on the spring of the Air Arms guns compared to German guns of similar power. Some of the parts on the Air Arms guns do seem a bit dainty and I question their realistic lifespan. The Weihrauch guns, if anything, is overbuilt like a tank. But they also handle as such in some ways. Also, when it comes to either brand's underlever, I feel it does a disservice to either not to scope them. To get the potential out of either, you have to mount a quality optic.
