A shorter barrel results in a loss of velocity, which effects the terminal ballistics of the round when it hits the target.
Second, a laser is useful in situations where you are unable to use any other targeting mechanism, such as in confined spaces where you cannot get a proper sight picture, military applications where night vision is being used, or as a training aid. Using a laser as the primary targeting mechanism on a carry gun is a poor idea. The reason is that it takes longer to chase down and reacquire the dot that it does to properly realign iron sights or point shoot. The idea that a laser is a good targeting mechanism on a handgun is an urban myth for all but a few extremely rare circumstances.
In my highly prejudiced and biased opinion, the Sig P938 is about the best pocket gun you can get. While its a little larger than the LCP and friends, it's a 9mm rather than .380, shoots more accurately, is more controllable, has real night sights, and you can put a few hundred rounds through it without excessively fatiguing your hand. Plus it's a Sig! Whether your going to carry it in a pocket or in the waistband, a Remora holster works really well.
You now are $0.02 richer, don't spend it all at once

It's an urban legend that a longer barrel equals greater accuracy. It doesn't, it equals greater velocity. Frame size and ergonomics do play a role in the person who's holding the pistol being able to aim and follow through properly, as well as minimizing their arc of movement. That's why I recommended the P938, its a little bigger than the LCP and friends, but that slight increase in size gives you significantly better ergonomics and controllability, real sights, a slide that locks back on an empty mag, etc.
A longer barrel with a higher muzzle velocity will also result in better terminal ballistics and longer range, which are the real advantages of longer barrels, not accuracy.
