I had a Ruger Speed Six with a 2 3/4'' barrel
I have a Glock 27
Fair comparison since the revolver barrel length doesn't include the cylinder, but the semi does include the chamber.
Chrono average for 5 shots:
Speed Six: Federal 125 gr. JHP magnum @ 1,248 fps / 432# KE
Glock 27: Speer Gold Dot 155 gr. @ 1,134 fps / 442# KE
Glock 27: Winchester Ranger T 165 @ 1,116 fps / 456# KE
The Glock 27 slightly trumped the snub .357 in both bullet diameter and KE.
If capacity and follow up shots are taken into consideration, the Glocks advantage increases further.
Criminals and psychos are mobile and my show up in "good" areas unexpectedly, carry accordingly.
Carry the gun you would you would prefer to defend your life with, in the off chance you have to.
