"New" HK HK4 - HKPRO Forums
Jun 23, 2021 · As mentioned above regarding the HK4's receiver being weak for the 380 round, I've heard the same thing about the Mauser HSc, even though it has a steel receiver.

From the workbench: A HK4 cautionary tale | HKPRO Forums
Mar 3, 2019 · The HK4 is one of those pistols that I have long admired from a distance but somehow never seemed to acquire. The P9S always seemed to take priority.
