Shootz.  I understand your issue and had the same problem on my 1006.  I can see in the picture that the plunger at the end of the slide release is stuck underneath the side plate assembly.  This is likely causing the slide to not stay open when a mag is in the gun.  This results from too much play on the side plate assembly.  Take off your grip and you can see the issue.  At the bottom of the side plate assembly there is a fork that pivots on a pin.  Likely this fork has spread, and is causing the excess play/excess pivoting.  When it pivots high, the plunger slips underneath the assembly and gets stuck.  Best thing to do is call S&W and get a replacement part (item #66 - side plate assembly).  Part is very inexpensive.  A gunsmith can replace it for you, but it's easy to do yourself.  Use a punch to chase out the pin for the side plate assembly.  Leave the punch in.  Then push the pin of the replacement side plate assembly into position, chasing out the punch.  Carefully snap the fork onto the pin at the bottom of the side plate assembly.  This will fix your issue and you will quickly find the 1006 to be the best handgun you will ever own.  Take your time and you'll fix this issue.  Enjoy.
