The Glock 27 is the only gun I’ve ever fired that I hated. A few years ago I put one magazine through a G27 one of my coworkers owned. It felt like someone was smacking my hand with a baseball bat and my strong hand was tingly, as if it had been asleep, when I finished. I politely handed the gun back to my coworker and told him I was glad it worked for him. I had a better time putting full power .357 loads through a Riter LCR.
