I have a 38 special revolver. What is the difference with 38 special & 38 super?
My daughter used one of the Sig P2?? in 40 caliber when she was with the SFPD. Really liked it.
The .38 super is an automatic cartridge. It is identical on the outside to the old .38 auto but is loaded hotter. It has just a tiny rim on which it headspaces, at least in older guns. It was determined long ago that auto cartridges which headspace on the case mouth are more accurate so many modern .38 supers do just that.
The .38 special is a revolver cartridge, a very old one.
Interestingly there have been autos chambered for the .38 special and I bet there have been revolvers chambered for the .38 super. The .38 super is a little hotter than the .38 special.
The .38 Super is a semi-rimless round, basically a very hot .38 ACP. It will not interchange with the .38 Special, but duplicates the 125 grain loading of the .357 Magnum.
