I'm not sure if I have the right to answer on this topic, seeing as the only time I "carry" a Pistol or Revolver is when I'm outside city limits and shooting at a friends farm, or range, etc. Also I only own two revolvers at this time, both I would trust in a worst case senerio (hopefully never happens). One is aCommercial made Post-WWII Webley & Scott Ltd. Mk. IV .380" Revolver, the other is a 1966-1967 era S&W Model 10-5 .38 Special Revolver with a standard 4" barrel.
If I had to choose which to trust a bad situation, it would be the S&W Model 10. The Webley is a great revolver, really enjoy shooting it, but I'd rather have a .38 Special than having a .380" (aka .38 S&W) in a crisis. Other than hearing some people not like the .38 Special Cartridge, I have not heard much bad said about the actual S&W Model 10 (or many other K-frame S&Ws) Revolver.
Thanks
