The *best* you're going to do is to buy a quality weapon from a reputable manufacturer, do all required preventative maintenance on a fixed schedule, properly lubricate it, use quality magazines, and use ammo from a reputable manufacturer.
That's the easy part.
At that point, the most important thing is for you to train so you know how to utilize the weapon and quickly clear any malfunctions that occur.
