I am a little more confident about the effectiveness of my LCP, since adding a Crimson Trace laser sight. A .380 round needs to be fired with a fair amount of precision, to have a decent chance of being effective against the worst case scenario-type of attacker.
The little gun is quite capable of shooting with the necessary precision, IF the shooter can do his job. I practiced with mine a lot, before adding the laser, and eventually was able to achieve 'pie-plate' precision, out past 10 yards.
Since adding the laser sight, I can hit much smaller targets, and do it quicker, and from even further away. I recommend it, highly.
