I have an FM Hi-Power that came without the magazine disconnect. The first time I took that to the range, I was very glad that we left the slides locked back after the magazine fed the last round. I thought the trigger was a touch lighter than my usual shooter, and took a closer look down the ejection port. Sure enough, no magazine disconnect. Since then, I have mounted my .22lr conversion unit on the frame and left it there. If you get used to having the magazine disconnect, you kinda expect it to be there. It's all in what you get used to when you are shooting.
