Sort of a gun survey

All of a sudden, my Ruger LC9 was dropping the magazine when firing. I could not manually pull it out, but when fired....there she went. I contacted Ruger, sent it back to them and have now received it (Customer Service was excellent). They replaced the magazine latch but have yet tested the fix.

Anyhoo....the issue got me curious and I Googled the issue and NUMEROUS manufactures and models have experienced this problem. Yet my brother has said he hasn't. So I am here to ask.....

Have you ever had an issue with the mag dropping?
