Pretty much all in the title , after I installed the apex spring kit I figured I'd give ahead and remove the magazine disconnect safety parts (two levers,spring and pin) as well since it's bothersome to me (saw the weapon would still function without somewhere in a thread here) Well after I reassembled the weapon and saw everything was good I went to take another look inside and discovered that I can't remove the slide anymore. Any advice??? Will I need to take this to a gunsmith?
