So first hi everyone new member , from FL recently bought a cm9 as my first ever pistol or firearm of any kind . Having little experience with guns I don't have much to compare but I hit the target consistently and it feels comfortable enough in my hand and I like the gun. Having finished the recommended "break in" periods I ran into one jam since then nothing when firing, BUT ( obviously there's a but) when I insert a fresh mag into an empty gun the slide stops halfway back unless I physically push the slide stop up while racking am I doing something wrong? Didn't happen when I first got it.
