My S&W 66 with 4" barrel is probably my favorite as it was also my duty pistol during my very brief foray into law enforcement. If not for the number of raccoons I've been finding on our walks and the recommendation to use standard velocity ammo, it would be my preferred walk about gun.
Not sure I follow that... The M66 fires both .357 Magnum and .38 Special, either one of those will do in a coon pretty handily.
