As above you need to own both really... nobody can be really, truly happy in themselves until they do. And a Steyr.
However much I love mine though, I would not buy an HW75 at the new price. I would get an HW40 at half that and put the rest toward my HW45 ...
Or if serious paper punching was the aim I'd put the lot toward a proper 10M SSP like a FAS 604 or a FWB.
Older 45s are better built IMHO and usually make higher power. They also don't have the Tru-Glo sights which is fine by me as I don't like em.
