Reply #66: Depends on the gun and the shooter...

[benEzra]

a short-barreled handgun is not inherently inaccurate, but it is harder to shoot well than a full-sized handgun due to the shorter sight radius and less moment of rotational inertia (making recoil a lot snappier).

Massad Ayoob once demonstrated 80% to 100% hit capability on a B-21 law-enforcement trainer target (that's the human-sized silhouette) at 100 YARDS with several makes of off-the-shelf .38 snubbies for a legal case in which he was called as an expert witness. I personally don't own any snubbies, but my 3.5" barreled S&W 3913 9mm is accurate enough to hit a 24" steel disk 7 for 8 at a measured 110 yards from a braced position, and that's only half the size of a B-21.
