Type-4 malfunction:
this is pretty uncommon, and if it ever happens to you when you are practicing with your gun at the range, throw the gun away and get a different model! This malfunction is where the slide does not go back into battery after firing. This might happen because your guide rod or guide rails are really gummed up (to the point where you might as well put some chewed gum in there), your guide spring is too weak or your chamber design is bad. Either way, modern semi-automatic pistols should never have this happen.
If this happens when you rack the slide, and ride the slide forward (like you should not be doing), it isn't as much of a problem, but if it happens after you fired a round, that's when you should start shopping for a new gun.
If this malfunction happens in the middle of a gun fight it may be detrimental because you may feel the slide not go back into battery and you try the tap, rack/flip, but the slide still won't go back into battery. It may take a little bit of time to figure out what is happening. Ultimately, a single second is a very long time in the middle of a gun fight to find out what is happening to your gun.
