Why did HK change the proven dual-recoil spring set up from the USP .45 and put a more conventional recoil spring (w polymer buffer) into the HK45?
The recoil of the HK45 is not bad, but a USP .45 has definitely a much smoother perceived recoil.
I'm just curious.... there should be plenty of "space" in a full size pistol for a more advanced dual-recoil spring system versus the old-school spring & buffer set up (the buffer does nothing to reduce perceived recoil... it just keeps metal from banging on metal...)
