It is important to take a few moments after cleaning to make sure you gun is assembled correctly. With a handgun you should make sure that it will fire double and single action (if applicable), stay at slide lock manually and with a magazine, and release from slide lock. Otherwise you could end up on You Tube or worse, dead.
