>>4005143they're square, but not in a bad way. makes them easy to clean off with no weird crevices on the outside
surprisingly comfortable two handed grip, although it does give away its boxiness one handed (why would you bother though)
only real gripe is I'm somewhat autistic and have a hard time holding the disassembly leverSSS down while releasing the slide because the factory slide release is like flat metal that you can't actually apply enough force to release the slide, but maybe I'm just gay
