I would rate the recoil of the HK 45 as slightly less than a 1911. Considering it's quite a bit lighter than a 1911, that's pretty good.
+1. My USP45T shoots softer than my HK45 and my HK45 shoots softer than my friends government size Kimber. The differences are not that great and some may have a hard time telling the difference unless they are being shot back to back.
