I was just wondering if anyone knew why so many people are dumping their shadow systems MR920 right now. I just got one and put 300 rounds through it with both the p-mags and factory glock mags including a 33rnd and had no issues at all. I know there was some talk about mags falling out but I did not incounter that. I know 300 rounds is not a tone but I figured that would show any issues and break it in a little. Plan on using for my daily carry off and on and wanted to see if there are issues I am unaware of.
