Guns have seen the benefit of hundreds of years of improvement, they are now incredibly reliable tools despite the fact that they basically operate via partially contained explosions which put a tremendous amount of stress on parts. Modern guns have been streamlined and refined to an enormous degree. When you pick up a gun you want it to work, because the assumption is that it working is going to save your life. The last thing you want is to add delay or unreliability to using a gun. And while having your own gun used against you is a concern it's much less of a concern than having a gun work reliably.
