Don't revolvers lose velocity because so much gas escapes between the cylinder & barrel?Again, Greg Ellifritz, the author of the Buckeye Firearms Association study, determined that the pistol rounds he studied were all so close in terminal performance that he shoots 9mm... He's an LEO, a respected firearms trainer, and an educated guy, and he doesn't base his conclusions on marketing hype or emotion.
One of the issues with researching 357sig effectiveness is the lack of LE shootings data for the round... 357mag data shouldn't be mixed with 357sig because revolver barrel lengths are measured differently than semi-auto barrel lengths- revolvers use actual barrel length while S/A pistols include the chamber in their barrel lengths, which means data from LE shootings with 357mag enjoy about 1.25 inches more barrel length and velocity advantage over 357sig... An example would be an S&W 357mag revolver with a true 4 inch barrel versus a Sig p229 with a barrel an inch shorter because the chamber isn't barrel length.
I'd urge anyone interested to read the entire study at Greg's website:

I remember some YT video explaining why you don't want your support hand in that spot when firing a revolver, the gas and unburnt powder shredded a hotdog in the demonstration.
