Think of the bench press as the ancient oak tree of the fitness world. It's solid, it's stood the test of time and it's grown a ton of branches. Those branches are, of course, a whole lot of benching variations.
You can bench with dumbbells, bench on an decline, bench on an incline and bench to your heart's content with all sorts of grips, with each tweak to the technique intensifying your engagement of specific muscles. With a wider grip, you're still reaping the basic benefits of the traditional bench press, but you put a little more focus on the outer chest muscles and may even increase the total amount of weight you can press.
As a subtle variation on the standard, the flat bench press, a wide-grip technique still covers the same basics. This exercise puts most of its focus squarely on working the pecs (specifically the pectoralis major, or "lower pecs"), but the upper pectoralis major, the anterior deltoids of the front shoulder and the triceps are also engaged as synergists -- muscles that help other muscles complete a movement.
While those muscles are synergizing, the bench press also recruits the biceps as dynamic stabilizers. So you might just get invited to the gun show after all.

A little shift in your grip, just a few inches beyond the standard barbell benching grip, also shifts the standard bench press' focal points a bit. This small tweak reduces the lift's range of motion, which places a bit more focus on the outer portions of your pecs, particularly the upper-pec muscles called the clavicular head.
Perhaps more noticeable than the difference in chest engagement is this variant's effect on how much total weight it helps you press. Though it's not a world-shaking difference, two well-respected studies — a 1995 article in "The Journal of Strength and Conditioning Research" and a 1992 piece in the "Journal of Applied Biomechanics" -- report that a wide grip might just enable you to increase your load capacity by 5 to 7 percent.
Though greater weight resistance makes for more challenge and potentially more muscle gains, this small percentage means that the wide-grip bench press caters more to powerlifters than gym dwellers seeking to tone up.
With less range of motion, you'll be putting more weight and torque on your shoulder joints when you use a wide grip. This is especially true if you make the common mistake of flaring out your elbows when you press, so if you have shoulder issues, you should probably skip this one.
If your grip is too wide, you risk reducing your range of motion a bit too much, which will decrease muscle engagement and could lead to improper execution of the exercise. To head off these complications, think of a wide grip as roughly elbow-width. If you're focusing on your triceps, it's worth noting that a wider grip also makes for less involvement of the tris.
