Excellent revolvers for skilled shooters. For anyone else, such small, light guns are little more than a good way to develop a bad flinch. They are difficult for the inexperienced to shoot well, one reason many claim these guns are inaccurate and use the "gunfights occur at close range" excuse to compensate for a lack of skill.

For someone willing to practice sufficiently, it's hard to find a more useful gun for the intended purpose. Other than as a personal preference, lock or no lock makes no difference.
