Thanks. My spring assembly still works but like you I don't like the idea that it will simply fall out once the slide is removed. I've only put about 800 rounds through the pistol so far so it's not like it should be worn out or anything. This hasn't caused any issues, I would just prefer something a little more robust. I have also found that the OEM assembly can cause some issues if you don't take a couple of seconds to make sure everything is correctly aligned/installed. Again, I'm not saying it's a bad part I just would prefer to replace it.
